New energy automotive lithium battery safety measures

Lithium-ion rechargeable laptop battery  has been equipped with many portable products, but repeated incidents of fire due to battery failure and had to replace the problem of recovery. Various battery manufacturers and product manufacturers are working hard to ensure the reliability and quality assurance, but the problem still has not been completely resolved.
To this end, an interview with reporters in the safety of lithium-ion rechargeable HP laptop battery with the design of battery management circuit design technology, technical director of the Taiwan Olympic Celxpert Zhong Secretary rattan. Austria rattan MoliEnergy from Canada in 1987 when the company began working to set up battery charging circuit protection circuit and the development of design, at the same time he was director of technology NECMoliEnergy product development ministers and ministers, which are lithium-ion rechargeable battery development, such as peripheral circuits of the battery pack safety design expert . Recently started to develop large lithium-ion automotive battery, fuel cell and lithium-ion rechargeable battery, such as a hybrid battery hp PB992A battery ,hp PB994A battery.
Q: Li-ion rechargeable battery with the battery pack which is now being used for the field?
Austria rattan: the 20th century, 90’s, was a large number of batteries used in cameras, still cameras and personal computers, and later started with cell phones, game consoles and other electronic products. Recently, its use extended to the power tools, electric scooters and electric cars and other fields. Will also extend to the future of electric vehicles, industrial / consumer-type batteries in areas such as fixed.
Q: What experience battery change?
Austria Goto: first in the popularity of lithium-ion rechargeable battery car lead battery charger and even after discharge would not have been too dangerous, from the security point of view, easy to use. The lithium-ion rechargeable batteries need to be used with caution, to improve the security of electronic circuit technology has become indispensable. Later, a large number of lithium-ion rechargeable hp PB995A battery ,hp PP2182D battery for portable products, in order to enhance efficiency, the beginning of the use of micro-control of microcontroller.
In future, the lithium-ion rechargeable battery technology and circuit control technology will be further developed. Should strive to avoid not only dangerous, but also predict the risk of self-diagnostic system.
For example, forecast that the unit will lose the balance of the system response is very important. Lithium-ion rechargeable battery cell in series with the increase in the balance of an issue unit. Loss of balance when the unit, the battery voltage becomes 0V to reduce or, if the hp Pavilion DV1000 battery ,hp Pavilion dv2000 battery  continue to charge and discharge, fire and smoke on the accident-prone. This issue 10 years ago has been pointed out, but add in the protection circuit unit balance circuit, able to solve this problem.
Not only can take advantage of the protection circuit to avoid the crisis, but also able to predict this phenomenon and to take countermeasures will become essential. In addition, when the need to balance unit in parallel, voltage and resistance changes in response.
Security design, effectively accumulated over the past at the time of charging the double fault protection institutions (secondary protection circuit) for the fuse to cut off the circuit components, such as technology. And, further into balance with the protection circuit module and so on, to achieve a more secure design. Now also try to further improvements.
Q: Li-ion rechargeable battery has been full of universal history of the past 20 years, when the remains of fire accidents occur from time to time and such failure caused the recall. Why do not eradicate these problems?
Austria Goto: safety design technology is a long-term commitment, continuous improvement. But I believe that battery technology is now with the circuit technology and product design staff is not very good cooperative relations. The past, the three areas is essential to promote the development of close co-operation. 10 years ago, few manufacturers supply unit, the three have been collaborating to develop until the requirements of the mutual understanding of each other. Now, sometimes the battery technology and battery designers have to take orders from vendors, in accordance with their demands, increase energy capacity and reduce prices hp Pavilion DV4000 battery ,hp Pavilion DV5000 battery.
Sometimes over-improve the energy capacity of the cycle of the expense of battery life, and sometimes for lower prices, safety design to muddle through, and thus lead to accidents and failures.
In improving the energy capacity, the basic unit or increase the quantity and the use of the materials being developed adequate safety testing. Not a good way. Battery technology with the circuit technology and product design staff established a cooperative relationship between the need to fully carry out consultations.
Configuration, the battery design and manufacturing side the best side should make a consensus. For example, it can identify in advance of the battery-powered notebook computers need time to reach 3 to 4 hours or more. Now, at the airport and the plane can be recharged. Can also increase the time a number of battery-powered models do not need that long. Not only to compete in the energy capacity, the key is on the user’s point of view of security.
In addition, now does not allow mass production, a large number of sales, a large number of abandoned. Want to have to take this into account. In energy-saving plays an important role, and to shoulder the mission of environmental protection can not be a large number of discarded batteries. Should strive to develop more secure, long-term use of the battery.
Q: the future of lithium-ion battery energy density will be increasing attention to the issues that should be?
Austria Goto: volume in the same energy in a closed up, means that the risk from a step closer. 10 ~ 20 years ago have been found: the use of Ni (nickel), the capacity to increase the risk of very large hp Pavilion dv6000 battery ,hp Pavilion dv8000 battery.
Of course, in considering the safety of products before the actual operation, but in a mixed Ni or Mn (manganese), it is important to be prudent to ensure security. Previously, when I MoliEnergy, someone was nickel acid lithium-ion battery burn passthrough. Although the academic literature data well, but did not address the fundamental security issues. It should be noted that whether the products of manufacturers and products have been described in detail the user is not involved in some of the literature.
Battery pack design, the energy density increases, so should pay attention to safety and service life. For example, I think the design of the battery pack using the appropriate system, such as self-diagnosis is essential.
Q: Li-ion rechargeable batteries for future use will be expanded to hybrids, electric cars and batteries in areas such as fixed, the safety of these uses should be designed to pay attention to what?
Austria Goto: As mentioned above, with the lithium-ion rechargeable battery cells connected in series increase in the number of units will be the question of balance. The electric vehicles now in series with a lot of units, units of the imbalance will become big problem. Need to consider how the imbalance in separate cells and systems. Driving process, as a result of battery fire, smoke led to drivers not to panic and lead to traffic accidents is not possible. Hence the need for even lower speed, but also the vehicle to a safe place to guide the system.
Storage applications, lithium-ion rechargeable battery low self-discharge, the most suitable for storing electricity. Is the most suitable for solar cell and battery combination of wind power. Now, is in the process of development of 1kW-class home fuel cells, fuel cells are expected to support the use of start-up and storage of Li-ion rechargeable batteries.
Q: Most of the past stand in battery manufacturers and battery manufacturers to develop battery manufacturers control circuit. Easy to lose sight of the product of the local manufacturers, battery manufacturers should pay attention to what?
Austria rattan: the key is clearly recognized that the chemical battery technology, the electronic circuit technology, if they do not adopt two technologies, will not be able to with ease.
For example, once the motor manufacturers to change the structure and change the configuration, electronic and technical personnel will be transferred to the battery manufacturing sector. While the technical staff will design the circuit, but it will not take safety measures. Because of the need to master the knowledge battery, which will take time. Electronic technology is chemical-technical people to understand is not easy to train, able to grasp the comprehensive limited knowledge.
However, to understand the importance of cultivating a comprehensive talent not many operators. Originally, the power supply and battery is unpopular, it is not easy attention. Is easy to cost-cutting department. Therefore must pay attention to this point, but the operators do not know if this will be the development of the system and product problems hp Pavilion dv9000 battery ,hp Pavilion ZD7000 battery.
Currently unable to display their talent in Japan and the battery power is a large number of the flow of technical personnel from overseas. I am worried that the future development of the capacity of batteries in Japan will decline.
I have often heard that the computer’s motherboard causing deterioration of the electrolytic capacitor product failure, electrolytic capacitors do not understand the knowledge, will determine the overall quality of different products. The same battery. I am a circuit technology staff, in fact, I have not personally been manufacturing lithium-ion rechargeable battery, but I am fortunate that the battery technology in many companies to help increase staff knowledge of the battery. Therefore, I am quite understanding of lithium-ion rechargeable battery and characteristics of the structure.
Q: What aspects of the industry system problem?
Austria Goto: issues such as security key is active in the industry as a whole share. For example, nickel-cadmium (NiCd) rechargeable batteries, if repeated shallow shallow place, the capacity will be reduced; lithium-ion battery at full charge state and placed under high temperature will lead to deterioration, such as service life, these problems will take a lot of time to be product designers and users are well known.
Safety and risk-sharing if not, the consequences will be very serious. Battery design must therefore assume the responsibility to explain, manufacturers should also maintain a positive attitude to understand.
Recently, the world’s growing number of battery incidents. In Japan, organizations such as the battery industry every year in preparation for the development of safety standards, and many overseas companies are also no progress.
Some time ago, I observed the batteries overseas manufacturers, who were in poor conditions products. Even found that a mixture of cell debris. Japan need to lead the battery industry to improve the safety of overseas manufacturers.
Q: How should a young technical staff to increase capacity?
Austria rattan: fait accompli should abandon the concept as a concept to a new technical staff. How someone else how to do that on the technical staff did not previously been known as the Engineers (Engineer), and is known as the replacement of the division (Change-neer). Hope that still is an engineer and technical personnel.
From Japan to introduce new technologies, a large number of overseas manufacturers to redouble their efforts are. To promote basic research, the number of patent applications are also increasing.
While the battery in Japan is still leading the field. Fear behind and actively develop and master new technology is also the champions of Japan. I hope the Japanese battery makers can continue to take the forefront in the world hp Business Notebook 6510b battery , hp Business Notebook 6515b battery , hp Business Notebook 6710b battery.
 

Manganese electrode could make lithium ion battery have two times more capacity

As our increasingly wireless and gadget-filled world demands better screens and more complex functions, the underlying technology that may be showing the most signs of strain is also one of the oldest: laptop batteries. Threatened with replacement and subject to massive recalls, the battery technology that we all rely on has shown signs of draining under the stress. But help may be on the way: researchers at Argonne National Labs are presenting data (PDF) on a method that provides a big boost to existing lithium ion batteries.

The researchers were able to get charge capacities of well above 250 mAh/g (more than twice the charge held by lithium ion dell laptop battery currently on the market) simply by replacing one of the electrodes. The new electrode relies on a layered-layered structure that includes a lithium-manganese oxide component. The new material apparently transfers charge both by freeing lithium ions and by reactions involving the manganese oxide itself.

Theoretically, these reactions should add up to a charge capacity of slightly below the 250 mAh/g figure, but the authors were surprised to find that capacity came in over 300 mAh/g when tested at 50°C, leading dell inspiron 1525 battery to term the charging behavior “anomalous.” It doesn’t appear that they yet understand why it works so well, as their abstract says that “possible reasons for the anomalously high capacity and the electrochemical cycling stability of these manganese-rich electrodes will be discussed in this presentation.”‘

This new battery tech isn’t ready for prime time yet, in part because the manganese reactions are predicted to damage the electrodes themselves. Even though the abstract suggests that they are unexpectedly stable, performance does decline too fast for commercial use: by 16 percent in as few as 10 charges. The reactions also produce oxygen during discharge of the dell inspiron 1526 battery, which will have to be rid of in some way. But there’s reason to think that these problems will be overcome: in addition to allowing greater power capacity, manganese is much cheaper than what’s currently in use.

 

Battery Recycling Gas Station

Can those AA Alkalines go in your normal household garbage?
With so many batteries available, it is often difficult to know how they should be properly disposed; can you toss it in the normal household garbage, or should it be taken to a hazardous waste location? 

Everyday batteries include:

Alkaline Batteries (flashlights, calculators, toys, smoke alarms, clocks, etc.) are classified as non-hazardous waste by the federal government. Most U.S. states, with the exception of California, can include with their normal household waste. California requires disposal of these batteries in accordance with the California Universal Waste Rules.

Button Batteries (watches, hearing aids, toys, greeting cards, remote controls, etc.) come in a variety of materials. They often contain mercury, silver, or lithium, and should be returned to the manufacturer when purchasing a new battery. Alkaline button batteries and zinc/air can be disposed of with normal household waste.

Li-Ion Batteries (laptops, camcorders, cell phones, etc.) are classified by the federal government as non-hazardous waste, however they can be recycled.

NiMH sony vgp-bps2 battery,sony vgp-bps2a battery (power tools, camera, cell phones, computers, etc.) are rechargeable and can be recycled. NiMH are considered a non-hazardous waste in most U.S. States, with the exception of California. Check the California Universal Waste Rules.

NiCad Batteries (power tools, camera, cell phones, computers, etc.) are recyclable. NiCad is considered a hazardous waste by the U.S. government, and should be brought to a recycling facility.

Wet Cell Lead Acid Batteries, (automotives and tractors) also known as flooded sony vgp-bps3 battery,sony vgp-bps3a battery can be recycled at most retailers that sell lead-acid batteries.

AGM Lead Acid Batteries, (wheelchair, ATVs, home alarm, metal detectors, etc.) or Absorption Glass Mat Batteries can be reconditioned or recycled into new products. Collection services are available at most automotive stores, landfills, transfer stations, and service stations.

The Rechargeable Battery Recycling Corporation (RBRC), a nonprofit public service, targets four kinds of rechargeable sony vgp-bps5 battery,sony vgp-bps5a battery  for recycling: nickel-cadmium (NiCad), nickel metal hydride (NiMH), lithium ion (Li-Ion), and small-sealed lead.

The rule of thumb is that most rechargeable batteries are recyclable. Look for the RBRC logo or the standard recycling logo to know if your battery is recyclable. The US government states it is safe to dispose of alkaline and other non-rechargeable batteries with the household garbage. If you are concerned about the environmental effects, then it is time to switch to rechargeable batteries. Rechargeable batteries can be used over and over again, then recycled.

 

Do you know how to rebuild a Li-Ion battery pack?

Did you recently notice poor performance of your notebook Li-Ion battery?.Don’t be taken aback, this is happening even to the best battery! Now days Li-Ion batteries are widely used in portable devices due to there excellent energy to weight ratio and for the reason they are not suffering from “memory effect”.

These two reasons make them the best choice on portable devices, but not suffering from “memory effect” doesn’t mean it will last for ever! Chemical conversions inside the battery make it to produce electric energy but these chemical reactions aim to attenuate as time and charge cycles pass over.

When the hp pavilion zd7000 battery life drops significantly it’s time to search for a replacement, but you will recently find out that most of notebook batteries cost almost 1/3 to 1/2 the price of the laptop at the time you will need to replace the battery. So if you want to keep your laptop but don’t want to spend much money for battery replacement it’s time to think about rebuild it your own, replacing each individual cell inside the pack.

But before step on this you must consider many parameters messing around Li-Ion batteries, about the way they are charged and the way you must handle them.

In this article we will discuss how to handle Li-Ion hp pavilion zv5000 battery to avoid any malfunction, the precautions you must take, the way Li-Ion batteries are charged, the protection circuits used and finally you can find a step by step guide on how to reconstruct a Fujitsu - Siemens Lifebook S-Series FPCBP25 battery pack. This guide can also be read as a tutorial on how to rebuild other kind of Li-Ion battery packs except the one we will use here.

 

Long-term strategy for the United States is: the future of fuel cells required for the vast majority of hydrogen from renewable energy resources in the production of access

U.S. hydrogen fuel cell technology development - from the fossil energy system to a hydrogen energy system and the diversification of a major conversion

Energy system from fossil to hydrogen as the carrier to the new system and the diversification of energy conversion, even though seemingly incredible, but it is not unprecedented. Countries in the world until the mid-19th century is still based on its energy system as the main means of transport livestock to wood heating and cooking. Today the formation of coal, oil and gas fossil energy systems and transportation fuel and electricity energy is everywhere-dell xps m140 battery,dell xps m1210 battery, dell 6y270 battery, it has been difficult to distinguish between functions of a modern society out.

It may be in the current energy system to the next generation of the edge of the conversion and diversification. Today, including the United States, Japan and other developed countries, as well as China, Brazil and India, strong economic growth in developing countries and the international community, a strong awareness of hydrogen as a future clean and sustainable energy system, a key, it is important component. Future hydrogen energy system is an important characteristic of hydrogen as a fixed power supply, transportation, industrial and residential, commercial use of an energy carrier, hydrogen will become a new energy system for the global economy, social development is not used exhaustible energy resources.

Because hydrogen is an energy carrier, is currently in production, storage, transport and use of such areas as technology development is still in the stage of technical maturity, hydrogen will be mainly from the acquisition of cleaner production technology. Hydrogen from electrolysis of renewable energy access, or from the use of fossil fuel carbon sequestration through the restructuring process of the solution after the acquisition. Hydrogen can be like oil, natural gas and other fossil energy is effectively stored, truck or pipeline transport. When the hydrogen for fuel cells, turbine or generator to produce electricity, it is the water main by-product.

Highly concerned about the United States of hydrogen and fuel cell technology development, its purpose is: In the short term, fossil energy use due to a large number of serious greenhouse gas emissions by the enormous international pressure to bear, so far the U.S. government have not signed the United Nations issued in 1997 “Kyoto Protocol” developed countries should shoulder the provisions of the emission reduction obligations, the Bush administration has recently made many times will not sign the document, the United States and the strengthening of hydrogen fuel cell technology development is to show a positive attitude. Another consideration is the hope that the United States through high-tech development, create more employment opportunities, the country’s industrial structure adjustment and upgrade their products in the international market competitiveness and to increase the current energy security and reliability of electricity supply needs. In the long run, as the world’s mineral resources, especially oil resources will become depleted, there is an urgent need to find a new energy resources or products dell 75uyf battery,dell c1295 battery,dell gd761 battery, to the next generation energy system for the conversion and diversification of the technical preparations to do the full system and a long time accumulation of operating experience.

Generally speaking, the development and utilization of hydrogen and fuel cell technology has many advantages:

• Can make use of the United States a large number of resources and different production methods, means hydrogen fuel;
• Reduce demand for imported oil, especially in the transport of oil resources required;
• Fuel cell can power transmission grid system is not able to meet the supply, the emergency start to fill the shortage of electricity supply, electricity supply has played the role of the peak;
• Can significantly improve air quality in the United States, the atmosphere, so that vehicle exhaust and clean use of fossil fuels in electricity production system is close to zero emissions.

Speaking from principle, hydrogen fuel cell is electrolysis in reverse reaction, the air in the mixture of hydrogen and oxygen to produce catalytic electrochemical reaction current, heat and pure drinking water. In addition to the characteristics of zero emissions, the fuel cell can be higher than the internal combustion engine 2 to 3 times the efficiency of the fuel cell power generation makes it the ability to work to obtain a wide range of applications, including: portable (50 ~ 100 watts) and the fixed station ( 1 ~ 200 MW). Although fuel cells have the service in all aspects of the economic potential of the area, but today they are in terms of price than the internal combustion engine is also relatively expensive, further development of the future will be to improve reliability and reduce costs in order to have economic competitiveness.

1. To hydrogen as a carrier of energy conversion system and the diversification of energy supply is a strategic choice

(1) the United States energy consumption, demand forecast
(2) U.S. oil production, consumption
(3) the United States transport energy strategy
(4) the development of fuel cell technology the United States road map

To this end, the United States the development of fuel cell technology is the basic road map:

• In 2015 to develop fuel cell technology can be carried out after the success of business kd476 decision-making;
• 2020, fuel cell vehicles is still in development stage, but during that time, in essence, the success of the technology not have any impact on the development of a large number of imported oil this trend;
• After 2020 may reduce the oil imports and oil fields in the consumption of transport;
• If the 2040 large-scale use of fuel cell vehicles a breakthrough, then the amount of light oil per day can reduce the 11 million barrels, equivalent to the amount of U.S. oil imports.

① Solid State Energy Conversion Alliance (SECA) program

② Department of Energy and the American Automobile Association (Freedom CAR) plans to

In short, as a result of fuel cell technology and energy efficiency, renewable energy technology development and wide application of strong, such technological breakthroughs and large-scale application in a certain extent, a significant reduction in the production and emission of greenhouse gases. However, despite the fuel cell has the potential of national interests, but it is in the current technological development, the need for capital investment in high-intensity running and long-term access to technical and economic indicators of the accumulation of these factors severely limits its commercial pre-set process. Based on this, the current U.S. government funding, technology development, testing fuel cell technology research with commercial applications, such as the value of the model will continue to play an important role.

2. The source of hydrogen

Long-term strategy for the United States is: the future of fuel cells required for the vast majority of hydrogen from renewable energy resources in the production of access. For example, the use of wind and solar energy dell 75uyf battery,dell c1295 battery,dell gd761 battery converter steelmaking technology of water electrolysis to obtain hydrogen; the use of sunlight or light from biomass catalytic hydrogen production methods; nuclear energy (using thermo-chemical process or electrolysis) is also an optional way. Make use of these methods as a result of increased diversification of energy sources, can significantly improve the U.S. national energy security.

The near term, hydrogen from fossil fuels will be able to (such as petroleum and natural gas) or the use of electrolysis to obtain the solution. Existing projects in the United States arrangements, the main purpose of these processes is to improve the cost and efficiency. Electrolytic method of producing hydrogen in the near future (from the distribution point of view) can be achieved, but its drawback is that use of the existing methods of electricity production, will not be able to produce energy, the environment in Iraq the ultimate efficiency; carbon dioxide absorption and to deal with the problems once they become reality can be used in this way will be from fossil fuels in the production of hydrogen, which will minimize the large number of greenhouse gas emissions.

International Co-City Japan and the United States reaction to the purchase of

According to overseas media reports, the international market price of cobalt in 2006 turned into the fall, and in February, after the bottom fell, with the strong growth in market demand, supply shortages, from the beginning of March the price rise become more evident. Strategic metals markets in Europe Rotterdam warehouse delivery for 99.8% grade premium grade cobalt, in February of this year fell to 12.75 ~ 13.25 U.S. dollars per pound, the has been increased to more than 15 U.S. dollars, 99.3 percent cobalt grade premium from 11.5 ~ 11.7 U.S. dollars rose to 13.75 ~ 14.5 U.S. dollars. At the same time, the actual current senior U.S. spot price of cobalt increased to 14.25 U.S. dollars per pound, the Russian Co-99.3%-level export price rose to 13.25 U.S. dollars, Zambia delivery price of 13.25 U.S. dollars, the Australian company BHP reported in Asia, Europe and North America, prices rose to 14 U.S. dollars.

According to industry estimates, global cobalt demand in 2006 up to 65,000 tons in 2007 to more than 70,000 tons. The main reason is the world’s airline industry, land-based gas turbine power stations and military arms of the active industrial production led to a marked increase in the consumption-cobalt alloy. It is understood that China will in the next 10 years to buy 180 billion U.S. dollars worth of power generation equipment, no doubt will lead to increased consumption of cobalt. The supply side, despite an ample supply of cobalt raw materials, but a serious shortage of refined cobalt production capacity. In this case, even if the capacity of refining cobalt production at full capacity, it is estimated that the market is still a shortage of refined cobalt supply and demand of 3000 tons. For this reason some people in the industry predicted that the end of the year for sustainable high-quality cobalt price climbed to 30 U.S. dollars per pound. Also has the trading community that the recent price of cobalt can be up to 16 ~ 18 dollars, because a large number of new cobalt smelting dell xps m140 battery,dell xps m1210 battery, dell 6y270 battery capacity by 2007 difficult to put into operation.

In addition, Russia Krasnoyarsk Connolly recently reported 99.3% grade for the class of cobalt base price also increased to 11.85 U.S. dollars per pound, but the company’s actual sales in the open market price of more than 13 U.S. dollars. The company is only a very small amount of a selective buyer of the company, and along with the revitalization of Russia’s aviation industry, tend to increase consumption of cobalt, it is estimated that the future will tend to decline in the export of cobalt.

Due to the rapid rebound in the international prices of cobalt alloys, as well as Japan and the chemical processing industry demand, some consumers worry about the future, Japan will further increase prices even higher, so they choose to move into the spot market to buy cobalt, or even at all costs. Japanese imports in December last year the spot price of cobalt 99.8% level has been increased to 16 ~ 17 U.S. dollars per pound, although in February this year, 1 to drop slightly, but the recent re-pricing of imports rebounded to 14 U.S. dollars per pound CIF. According to Japanese traders said that the Japanese battery industry accounted for about cobalt cobalt consumption to 60% of the total demand, and the industry under the forward contracts are usually imported cobalt was still adequate inventory, so buy on the spot market is currently little interest in cobalt.

At the same time, U.S. consumers to buy cobalt is also very active, especially in the spot dell kd476 market imports from Russia. However, 99.3 percent of Russia’s supply of cobalt-level is very scarce, and even the recent delivery of cobalt has been sold out. Russia supplies the current level of 99.3% cobalt prices and the market price of 99.8% of the difference in class is gradually shrinking, and even less than 1 U.S. dollars per pound. Some consumers are also the same by the United States the annual import turnover of the contract, so from the spot market is not buying.

It is reported that Kim Yi Science & Technology Park will conduct the second phase project of deep processing of tin and the production of nano-materials projects, the entire park plans to invest 500 million yuan.

Scientists invented the fuel cell enzyme

Oxford University scientists have invented a device to provide an impetus to the electronics of the fuel cell enzyme, which is the battery consumption of atmospheric oxygen and hydrogen. The enzyme used is from the natural world for the use of hydrogen metabolism in the isolated bacteria. The characteristics of this enzyme is a highly selective, able to put up with the traditional fuel cell catalysts has a poisoning effect of the gases, such as carbon monoxide and hydrogen sulfide. The researchers said: As a result of this enzyme to the growth, so compared to other hydrogen fuel cells by use of expensive platinum catalyst is a cheap, renewable battery.

By Professor Fraser Armstrong led the design of the research group including the fuel cell has two electrodes coated with the enzyme. They are filled with normal air, and add a small amount of hydrogen in the glass tank. As the catalyst selectivity and tolerability, so the gas can be mixed without the need for expensive fuel separation membrane.

Armstrong said: The study resulted in greater fuel-cell applications of space, as has been the cost of fuel cell applications are the main issues, but can not guarantee that the source of cleaner fuel and the need for real-time power.

Solar cell production capacity in China in 2007 accounted for 16.7 percent of global

According to China’s Taiwan, “Industrial Technology Research Institute” under the Optical Technology Center (PVTC) is expected to the end of 2007, the global solar cell production capacity is expected to reach 48,000 kilowatts (GW), of which the mainland will reach 16.7 percent global market dell latitude d830 battery,dell latitude x300 battery share, more than Taiwan, about 10%. PVTC Taiwan in 2006 is expected to remain slightly ahead of the mainland.

PVTC expects Suntech China, Nanjing PV (Nanjing PV) solar cell manufacturing plant the two together will reach about 12.5%, if the other new entrants into the mainland is expected to reach a global market share of 16.7%, far exceeding Taiwan manufacturers.

It is worth mentioning is that Suntech an annual production capacity of 2006 is expected to more than 300 megawatts (MW), expected from the world’s eighth in 2005 jumped to fourth place, behind Japan’s Sharp (Sharp), Germany’s Q - Cells and Japan’s Kyocera (Kyocera). PVTC pointed out that the positive into polysilicon production and a huge domestic market demand for solar cell production capacity in China a major factor in the rapid growth.

China’s renewable energy policy incentives, the expansion of growth in demand for solar industry

In new renewable energy policy incentives, China’s domestic supply chain in all areas toward the expansion of solar power in the direction - of polysilicon feedstock, wafer, cell and module. Investment bank Piper Jaffray analyst Jesse Pichel said in a report, China last month promulgated a renewable energy project involves 3.5 billion U.S. dollars of investment, designed in 2010 in the domestic solar power generation capacity to 500 megawatts. China also plans to solar power by 2020 will amount to 3,000 megawatts in 2050 to 6,000 megawatts.

“In China, promulgated in February of renewable energy plan under the impetus of China’s solar energy needs are expected to be substantial growth over the next few years.” He said, “apart from less than 200 dollars a month in labor costs, China’s solar energy company may also be lower because the cost of management, research and development costs and external costs to benefit. ”

According to the analyst, by 2008, China’s total module production capacity from 450 megawatts (MW) increased to 1,200 MW, the domestic solar cell production capacity increased from the current 200MW to 1,200 MW. 2005 China wafer capacity of 100MW, is expected to grow in 2008 to around 800MW, mainly from the signing of polysilicon supply, as well as contracts for the supply of a large number of polyethylene.

He said that China’s solar manufacturing equipment industry will also expand. At present, the three Chinese polysilicon manufacturers monopolized the domestic dell latitude d800 battery,dell latitude d810 battery,dell latitude d820 battery market, but it is still a shortage of supply of material.

“By 2007, Sichuan Xinguang silicon industry is still at an early stage of production and construction, planned in 2008 to 1,250 tons of annual production,” Pichel said, “LSCS current annual capacity of 300 tons, production capacity in 2007 reached 1,000 tons. Another year the current ESM about 100 tons of production capacity. “polysilicon high price to 200 U.S. dollars per kg, most solar manufacturers can accept the OEM price is about 170 U.S. dollars per kilogram.

 

Statistics show that China’s light industrial products in 2005 reached 194.13 billion U.S. dollars, up 23.53 percent

EU and new tricks to play against the new battery directive

From Ningbo Inspection and Quarantine Bureau was informed that recently, the European Union put forward a new draft 98th directive batteries, the batteries directive in principle, be amended to reduce the hazardous and non-hazardous waste, the number of cells, and increased recycling of these products contain materials. It is reported that once the Bill comes into force of the directive will ban all alcohol concentration of more than 0.0005% of mercury in dell latitude d510 battery,dell latitude d520 battery,dell latitude d600 battery and battery (mercury content of no more than 2% except for the button cell) and by weight contains more than 0.002% of cadmium batteries and the battery light to enter the European Union market. In addition, the new directive will also require to ensure that all batteries and battery recycling need to add the correct sign, the requirements indicated in the product, respectively, the chemical symbol of the metal.

The world per capita production of batteries in China more than four

At present, China is the largest production and export of battery. The world per capita use in China more than four batteries, my bike in both production and export share of world production and exports over 60%, there were a large number of light industrial products output ranked first in the world … … “15,” the period of the rapid development of light industry, its products not only meet the needs of the domestic market, but also contribute to the advantages of cheap in the world market.

21 journalists from the China Light Industry Federation, held the second Congress was informed that at present China’s watches, bicycles, sewing machines, batteries, beer, furniture, plastic processing machinery, daily-use ceramics, sea salt, electric light source and lighting products and home appliances, etc. air-conditioning industry, microwave ovens, leather footwear industry, the sports goods industry, books, musical instruments industry, piano, violin, guitar, metal products industry, metal and plastic tools for the plastic products industry, film production, and many other products in the world first. Paper and paperboard, plastics production ranks second in the world.

Statistics show that China’s light industrial products in 2005 reached 194.13 billion U.S. dollars, up 23.53 percent, which is equivalent to “Ninth Five-Year Plan,” the end of light industrial products-dell latitude d610 battery,dell latitude d620 battery of 2.74 times the volume of foreign trade, light industry exports China’s foreign trade accounting for more than a quarter of total exports. Furniture, household appliances, ceramics for daily use, culture and education, sporting goods, bicycles, watches, sewing machines, leather, electric lighting and lamps, pens, musical instruments, toys, glasses, and other industries down the world’s exports to the forefront of exports. Ceramics for daily use of which exports of world exports accounted for 65% of the total, exports of bicycle industry trade of the world’s total trade volume accounts for 70%, household appliances industry products exported to the world at present more than 200 countries and regions.

According to Chen in the light can be introduced in conjunction president in 2005, than the “Ninth Five-Year Plan” more than doubled in the late production of dozens of kinds of light industrial products. Including refrigerators, washing machines, air conditioners, vacuum cleaners, microwave ovens, electric water heater, electric baking utensils, rice cookers, dishwashers, mechanism of paper and paperboard, newsprint, paper products, furniture, gas water heater, dairy products, canned food, beverages , frozen drinks, fur clothing, the books, ink, photographic film, fragrance, plastic products-dell latitude d510 battery,dell latitude d520 battery, hand tools, household stainless steel products, candy, cakes, biscuits, instant noodles and umbrella.

China’s light industry technologies and equipment and product quality are greatly improved: the backbone of large-scale dairy enterprise technology and equipment to reach the international advanced level; washing the basic technical level of industry reach or approach international advanced level; paper, leather, plastics processing, lighting, batteries, etc. industry technology and equipment to reach the world advanced level. By the end of 2005, China’s light industry in China’s famous brand products 40% of brand-name products, many world-class product quality level.

New energy into the energy development will focus on

Sustainable Development Strategy of the Chinese Academy of Sciences, honorary head of the group not long ago, said Niu Wenyuan, the world’s energy development is accelerated from the “carbon-based energy” to “hydrogen-based energy” forward, “China’s energy strategy is not only a big topic, but also the world’s largest energy strategy proposition. ”

In the newly published by the People’s Publishing House “Who can drive in China - the world’s energy crisis and China’s strategy of” one book, said Niu Wenyuan, a breakthrough from the first “Light-harvesting protein” genes of biological photosynthetic energy efficient chip-to-large-capacity hydrogen fuel cells, hydrogen-based energy from the acquisition and transmission to the “Space Spider” energy network weaving, from -3 isotope helium surface on the acquisition and preparation of energy into controlled thermonuclear fusion, such as consumption, these new energy will gradually energy development path, “the central stage.”

“Energy has become China’s future development, one of the major bottlenecks.” Niu Wenyuan said that China’s energy strategy, on the one hand to firmly grasp the universal energy-saving, industry-wide energy saving, energy-saving society as a whole, “a key element,” not to relax On the other hand, did not slacken our efforts for the deepening of opening up new energy. “As an energy consuming country dell latitude d600 battery,dell latitude d610 battery,dell latitude d620 battery, China should be at the same time the consumption of traditional energy sources, energy development as soon as possible the next generation to take active steps to plan.”

According to authoritative statistics, Chinese people can be a one-time energy production per capita, compared with the world, with lower values. At the same time, the intensification of China’s energy level is still relatively low, a waste of a very serious situation. These data show that, on the one hand, China’s rapid industrialization and urbanization development, requires a large amount of energy to support, on the other hand, China’s energy-saving potential is very great.

This solar cell has a special gathering of power efficiency (PCE)

ScienceDaily (July 27, 2009) - dye-sensitized solar cells (DSSCs) will in the future for unmanned aerial vehicles (UAVs) for energy, because they have the best energy collection system, laptop battery and the situation in the absence of fuel for aircraft provide longer flying time.
University of Washington Multidisciplinary University Research Initiative (MURI) project team, in the researcher Dr. Minoru Taya, under the leadership is committed to a sky solar cell research - with a flexible film with a thin transparent conductive glass electrode. He found DSSCs is composed of organic materials, including dyes and moth eye film, to capture photons and convert them into electronic, in order to obtain high photon energy.
A few years ago, the group will be dye-sensitized solar cells mounted on a toy plane wing, the propeller to work correctly, but as a result of heavy use of solar cells, aircraft will not fly. After testing, they decided to use thin-film Apple laptop battery technology and the success of the aircraft to fly up.
“This solar cell has a special gathering of power efficiency (PCE), is a very clean source of energy, the machine can easily form in a helicopter covering a large area, low temperature can also be carried out to reduce the total cost.” Taya said.
The group is currently using dyes in DSSCs bionic PECs will be installed on its wing unmanned aircraft, to collect energy in the air.
Taya also said that “any air energy collector must meet some additional requirements, such as weight and in the air environment durability. If these can be met, A1175 battery , A1185 battery the aircraft can have a longer flight time.”
At the same time, research is challenging engineers DSSCs technology, can find the key to longer-lasting batteries, as well as how their technology to better compete with other air vehicles into one. The group also tried to determine how the wing in a helicopter to install solar cells and how to store the energy collected.
“Some of these problems will be in the United States Air Force Office of Scientific Research Multidisciplinary University Research Initiative of the hard work of researchers, in the next two years to be resolved. DSSCs in order to enable the transfer of the solar collector to the UAV’s machine wing, the more tasks there are still projects, other projects that need funding in order to resolve after 5 years. ”
Finally, the group hopes to design a larger, more flexible, with high-energy conversion rate of DSSCs, in order to achieve their goals. In general, the efficiency of solar cells will be reduced, therefore, the group is using high surface resistance of the metal grid, can greatly speed up the electronic transmission in order to maintain high efficiency.
 

New energy automotive lithium laptop battery safety measures

Lithium-ion rechargeable laptop battery has been equipped with many portable products, but repeated incidents of fire due to battery failure and had to replace the problem of recovery. Various battery manufacturers and product manufacturers are working hard to ensure the reliability and quality assurance, but the problem still has not been completely resolved.
To this end, an interview with reporters in the safety of lithium-ion rechargeable FK890 battery, GK479  with the design of battery management circuit design technology, technical director of the Taiwan Olympic Celxpert Zhong Secretary rattan. Austria rattan MoliEnergy from Canada in 1987 when the company began working to set up battery charging circuit protection circuit and the development of design, at the same time he was director of technology NECMoliEnergy product development ministers and ministers, which are lithium-ion rechargeable battery development, such as peripheral circuits of the battery pack safety design expert . Recently started to develop large lithium-ion automotive battery, fuel cell and lithium-ion rechargeable  Pavilion dv6000 battery , such as a hybrid battery.
Q: Li-ion rechargeable battery with the battery pack which is now being used for the field?
Austria rattan: the 20th century, 90’s, was a large number of batteries used in cameras, still cameras and personal computers, and later started with cell phones, game consoles and other electronic products. Recently, its use extended to the power tools, electric scooters and electric cars and other fields. Will also extend to the future of electric vehicles, industrial / consumer-type batteries in areas such as fixed.
Q: What experience battery change?
Austria Goto: first in the popularity of lithium-ion rechargeable battery car lead battery charger and even after discharge would not have been too dangerous, from the security point of view, easy to use. The lithium-ion rechargeable batteries need to be used with caution, to improve the security of electronic circuit technology has become indispensable. Later, a large number of lithium-ion rechargeable batteries for portable products, in order to enhance efficiency, the beginning of the use of micro-control of microcontroller.
In future, the lithium-ion rechargeable HP laptop battery  technology and circuit control technology will be further developed. Should strive to avoid not only dangerous, but also predict the risk of self-diagnostic system.
For example, forecast that the unit will lose the balance of the system response is very important. Lithium-ion rechargeable battery cell in series with the increase in the balance of an issue unit. Loss of balance when the unit, the battery voltage becomes 0V to reduce or, if the batteries continue to charge and discharge, fire and smoke on the accident-prone. This issue 10 years ago has been pointed out, but add in the protection circuit unit balance circuit, DELL laptop battery able to solve this problem.
Not only can take advantage of the protection circuit to avoid the crisis, but also able to predict this phenomenon and to take countermeasures will become essential. In addition, when the need to balance unit in parallel, voltage and resistance changes in response.
Security design, effectively accumulated over the past at the time of charging the double fault protection institutions (secondary protection circuit) for the fuse to cut off the circuit components, such as technology. And, further into balance with the protection circuit module and so on, to achieve a more secure design. Now also try to further improvements.
Q: Li-ion rechargeable Compaq laptop battery  has been full of universal history of the past 20 years, when the remains of fire accidents occur from time to time and such failure caused the recall. Why do not eradicate these problems?
Austria Goto: safety design technology is a long-term commitment, continuous improvement. But I believe that battery technology is now with the circuit technology and product design staff is not very good cooperative relations. The past, the three areas is essential to promote the development of close co-operation. 10 years ago, few manufacturers supply unit, the three have been collaborating to develop until the requirements of the mutual understanding of each other. Now, sometimes the Presario 2500 battery , Presario R3000 battery technology and battery designers have to take orders from vendors, in accordance with their demands, increase energy capacity and reduce prices.
Sometimes over-improve the energy capacity of the cycle of the expense of battery life, and sometimes for lower prices, safety design to muddle through, and thus lead to accidents and failures.
In improving the energy capacity, the basic unit or increase the quantity and the use of the materials being developed adequate safety testing. Not a good way. Battery technology with the circuit technology and product design staff established a cooperative relationship between the need to fully carry out consultations.
Configuration, the Sony laptop battery design and manufacturing side the best side should make a consensus. For example, it can identify in advance of the battery-powered notebook computers need time to reach 3 to 4 hours or more. Now, at the airport and the plane can be recharged. Can also increase the time a number of battery-powered models do not need that long. Not only to compete in the energy capacity, the key is on the user’s point of view of security.
In addition, now does not allow mass production, a large number of sales, a large number of abandoned. Want to have to take this into account. In energy-saving plays an important role, and to shoulder the mission of environmental protection can not be a large number of discarded batteries. Should strive to develop more secure, long-term use of the battery.
Q: the future of lithium-ion PCGA-BP2NX battery , PCGA-BP2NY battery  energy density will be increasing attention to the issues that should be?
Austria Goto: volume in the same energy in a closed up, means that the risk from a step closer. 10 ~ 20 years ago have been found: the use of Ni (nickel), the capacity to increase the risk of very large.
Of course, in considering the safety of products before the actual operation, but in a mixed Ni or Mn (manganese), it is important to be prudent to ensure security. Previously, when I MoliEnergy, someone was nickel acid lithium-ion VGP-BPS5 battery  burn passthrough. Although the academic literature data well, but did not address the fundamental security issues. It should be noted that whether the products of manufacturers and products have been described in detail the user is not involved in some of the literature.
Battery pack design, the energy density increases, so should pay attention to safety and service life. For example, I think the design of the battery pack using the appropriate system, such as self-diagnosis is essential.
Q: Li-ion rechargeable batteries VGP-BPS2 battery , VGP-BPS2A battery , VGP-BPS3 battery for future use will be expanded to hybrids, electric cars and batteries in areas such as fixed, the safety of these uses should be designed to pay attention to what?
Austria Goto: As mentioned above, with the lithium-ion rechargeable battery cells connected in series increase in the number of units will be the question of balance. The electric vehicles now in series with a lot of units, units of the imbalance will become big problem. Need to consider how the imbalance in separate cells and systems. Driving process, as a result of battery fire, smoke led to drivers not to panic and lead to traffic accidents is not possible. Hence the need for even lower speed, but also the vehicle to a safe place to guide the system.
Storage applications, lithium-ion rechargeable VGP-BSP13/S battery  low self-discharge, the most suitable for storing electricity. Is the most suitable for solar cell and battery combination of wind power. Now, is in the process of development of 1kW-class home fuel cells, fuel cells are expected to support the use of start-up and storage of Li-ion rechargeable batteries.
Q: Most of the past stand in battery manufacturers and battery manufacturers to develop battery manufacturers control circuit. Easy to lose sight of the product of the local manufacturers, Toshiba laptop battery manufacturers should pay attention to what?
Austria rattan: the key is clearly recognized that the chemical battery technology, the electronic circuit technology, if they do not adopt two technologies, will not be able to with ease.
For example, once the motor manufacturers to change the structure and change the configuration, electronic and technical personnel will be transferred to the battery manufacturing sector. While the technical staff will design the circuit, but it will not take safety measures. Because of the need to master the knowledge PA3176U-1BRS battery , which will take time. Electronic technology is chemical-technical people to understand is not easy to train, able to grasp the comprehensive limited knowledge.
However, to understand the importance of cultivating a comprehensive talent not many operators. Originally, the power supply and battery is unpopular, it is not easy attention. Is easy to cost-cutting department. Therefore must pay attention to this point, but the operators do not know if this will be the development of the system and product problems.
Currently unable to display their talent in Japan and the battery power is a large number of the flow of technical personnel from overseas. I am worried that the future development of the capacity of batteries in Japan will decline.
I have often heard that the computer’s motherboard causing deterioration of the electrolytic capacitor product PA3178U-1BRS battery , PA3191U-1BAS battery failure, electrolytic capacitors do not understand the knowledge, will determine the overall quality of different products. The same battery. I am a circuit technology staff, in fact, I have not personally been manufacturing lithium-ion rechargeable battery, but I am fortunate that the battery technology in many companies to help increase staff knowledge of the battery. Therefore, I am quite understanding of lithium-ion rechargeable battery and characteristics of the structure.
Q: What aspects of the industry system problem?
Austria Goto: issues such as security key is active in the industry as a whole share. For example, nickel-cadmium (NiCd) rechargeable batteries, if repeated shallow shallow place, the capacity will be reduced; lithium-ion  PA3191U-1BRS battery at full charge state and placed under high temperature will lead to deterioration, such as service life, these problems will take a lot of time to be product designers and users are well known.
Safety and risk-sharing if not, the consequences will be very serious. Battery design must therefore assume the responsibility to explain, manufacturers should also maintain a positive attitude to understand.
Recently, the world’s growing number of battery incidents. In Japan, organizations such as the battery industry every year in preparation for the development of safety standards, and many overseas companies are also no progress.
Some time ago, I observed the batteries PA3191U-2BRS battery , PA3191U-3BRS battery overseas manufacturers, who were in poor conditions products. Even found that a mixture of cell debris. Japan need to lead the battery industry to improve the safety of overseas manufacturers.
Q: How should a young technical staff to increase capacity?
Austria rattan: fait accompli should abandon the concept as a concept to a new technical staff. How someone else how to do that on the technical staff did not previously been known as the Engineers (Engineer), and is known as the replacement of the division (Change-neer). Hope that still is an engineer and technical personnel.
From Japan to introduce new technologies, a large number of overseas manufacturers to redouble their efforts are. To promote basic research, the number of patent applications are also increasing.
While the IBM laptop battery  in Japan is still leading the field. Fear behind and actively develop and master new technology is also the champions of Japan. I hope the Japanese battery makers can continue to take the forefront in the world.
