“Lithium-ion battery homogeneous competition is very serious.” Recently held in Beijing at the Sixth Beijing International pure electric vehicles, hybrid vehicles and parts cum clean energy show, a domestic business-related executives talk about lithium batteries exhibitors feel resigned: “You look at these booths, one by one company are lithium level of technology similar; our customers - but not even one vehicle enterprises appeared.” The person in charge that the new energy vehicle model after running the country to face real business to run next request will be higher, the threshold will be set higher standards. “Countries would undoubtedly lithium Biaozhun, 企业 access some move. Only by strictly the norms is possible so that the current homogeneous competition become into a business speed up its development, to market the momentum.” He said.
In fact, the power lithium battery-related standards and specifications in the country are in the process. “Power battery industry in the second half of this year there will be some GB or industry standard can, including standard sizes, Anquan Xing, Xun Huan Deng life.” Guo Jia Ji Hua 863 energy saving Yu Xin Qi Ju major Xiangmuzongti Zhuanjia Zu Chemical and Physical Power Technology Laboratory Battery liability expert Xiaocheng Wei told reporters recently, in addition to the standard battery, the state departments of electric vehicles are perfect for brewing a standard system, covering vehicles, batteries RN873 GW240 Inspiron 1525 battery , motors, charging facilities, part of the standard expected in the second half of this year announced.
Policy opportunities
“Comparison of lithium-ion batteries currently ‘hot’ applications more occasions can be said that lithium-ion batteries are now facing greater opportunities to develop the great potential.” Nonferrous Metal Research Institute Beijing Institute of Energy Materials and Technology, the Navy lieutenant senior Dr., with the expanding application of lithium-ion battery battery for some time will occupy a major share of the market.
Lithium-ion battery “hot” with the policy transmission information is not unrelated. June 1, the Ministry of Finance, Ministry of Science, Industry and Information Technology, National Development and Reform Commission jointly issued “on the purchase of new energy vehicles to carry out subsidies for private pilot’s notice”, on the plug-in hybrid electric passenger cars and ride car for a one-time subsidy. Apparent olive branch policy for these two types of models to the power lithium battery tilt Inspiron 1526 battery .
Side subsidies for private purchase of new energy vehicles formally launched pilot projects, one side is the public transportation field, “10 City 1000″ energy saving and new energy vehicle demonstration and extension of the pilot expanded to 20 cities. Attractive market prospects as a beautiful picture out slowly, then the internal power lithium battery company is ready?
“Now the power lithium battery company is well positioned to meet the demonstration run of preparation, but not well prepared to adapt to the market. It is hoped that the national policy of pulling for the new energy automotive products to market to prepare for the future.” Chinese Academy of Sciences Institute of Physics Fellow Huang Xuejie told reporters that the role of model runs in two aspects: First, the size of the market for a certain power lithium battery production enterprises up and running, we will never mention the technology matures, the accumulation of experience; second is solved in time demonstrate the problems exposed in the operation, and complete power lithium batteries and the vehicles running. Huang Xuejie that this stage needs about 2-3 years. “After 2-3 years there will be some power lithium battery in quality to meet the requirement. 2015, some enterprises do not need to subsidize power lithium battery will have a market competitive U4873 D5318 .”
Huang Xuejie have made the market competitive power lithium battery for a few indicators: by 2012, the energy density of batteries group must first meet the safety, environmental adaptability. Energy density of 120 Wh / kg power density of 1 kW / kg, cycle life of 2,000 times the cost of individual cells up to 2 yuan / watt when the following.
College of Chemistry and Molecular Dr. Huang Youyuan believes that the current power lithium batteries is also very difficult to meet the needs of commercial electric vehicles, the main issues: the cost is still too high; technology immature, the reliability to be verified; product consistency to be increase; and matching battery power battery management system still needs improvement, and improve reliability.
Xiaocheng Wei believes that the domestic lithium battery power to run the basic model to meet the requirements of electric vehicles, but also need the technical, cost, to further improve, more attention to safety and reliability. “At present, lithium battery power is running in demonstration vehicles to get a better application of technology has been verified and assessment. But the electric car to meet the requirements of ordinary people, but also reliability and cost, in-depth research to continue. In the present the basis of specific energy battery system will be increased to 100 Wh / kg, the driving range to 100 kilometers or more, and gradually improve and promote the electric vehicle technology advances, the ultimate commercialization of electric vehicles to meet the requirements Inspiron 6000 battery Inspiron 9300 battery . ”
Apparent gap
Experts agree that China’s power lithium battery technology and advanced level there is a certain gap.
HUANG You-yuan fully reaffirmed China Government in promoting the dynamic performance lithium battery applications. “As the Chinese government’s active promotion of domestic lithium battery in the application of power to lead the world, and accumulated precious experience in large-scale application of lithium battery power.” But he also pointed out that Japanese power lithium battery technology is based on automated production lines, consistency of better batteries; while most domestic power lithium battery technology is based on semi-automatic or manual production line, the battery is less consistently. And both lithium manganese oxide spinel or iron phosphate lithium battery, China and Japan are in the small-scale trial production stage.
Huang Xuejie that the power lithium battery technology at home and abroad in the gap mainly in three aspects: First, domestic battery and foreign individual indicators may be close to or even higher, but the overall index lower, especially in the battery life of the above; 2 is the reliability, consistency, there are large gaps; Third, the overall large-scale industry, but there are single companies small and too scattered problems Inspiron 9400 battery Inspiron E1705 battery .
“A big gap between high-end application market. Such as Japan in the control of raw materials, cell quality control, management control, etc. have been extraordinarily Yange, battery good consistency; Erwo Guo Although capable of producing high-quality of single cells, but cells consistent of quite different, applications will exist on the vehicle a short battery life, high cost range of issues. “Wei Navy believes that this gap is the country’s overall level of equipment manufacturing industry decision, not a single battery industry can change the short term.
According to Huang Xuejie introduced in Japan in the production of special equipment lithium battery power at least 5 years ahead of China, such as 600L mixing pulp machine, spray coating machine, hot and cold rolling machine. China achieved through the introduction of absorbing the majority of stand-alone equipment at home, but the single production and manufacturing precision equipment, there is a large gap with Japan, there is no domestic auto batteries assembly line. “Introduction alone can not solve the problem, to enhance self-development capabilities and equipment.” He said Inspiron XPS M170 battery Inspiron XPS M1710b battery .
“China and Japan than in the single battery, module, integration has a gap, this gap between the battery more integrated.” Xiao Chengwei that domestic battery business in the future may be a number of different development models: part of the enterprise specialized in the production scale of single cells; part of the company may be engaged in the size of the battery module production; part of the company will do the battery system integration, such as foreign Bosch, China, Johnson, like other auto parts enterprises. Can not simply say which model better, as long as the business under its own characteristics and technical capacity to play their respective advantages and expertise to do so refined, can be regarded as a good development model. ”
Person in charge of a lithium battery company, said: “power lithium battery industry is currently facing two characteristics: First, divide the product be used in many industries such as energy storage industries, automobile industries, different sectors of the lithium battery’s individual needs not the same; Second, for each industry, the short-board lithium urgent need to upgrade, such as reliability, consistency and so on GD761 TD347 . ”
Solution
Huang Xuejie in an interview process repeatedly emphasized: “a certain power lithium battery industry, give a training opportunity.” According to him, the Shanghai World Expo 1000 a new energy vehicles, 1 / 3 of the vehicles using the power lithium battery, the number of is not small. However, the maturity of the Japanese power lithium battery is better than China, which is the whole industry chain, level of development. “Our consistency in the quality of raw materials, the key material performance levels, equipment levels and an integrated battery indicator so obvious gap with foreign countries. The solution is nothing but two: First, the introduction and development of advanced high degree of automation equipment; 2 must rely on time, the number of accumulation. “he said.
“From a technical point of view, indeed constrained battery electric vehicle development, mainly in high cost and lack specific energy and cycle life to be improved and so on.” Huang Yu-yuan believes that these problems can be resolved in two ways: one be improved through technological advances; Second, the maturity of existing technology for the development of market operations and commercial models. Commercialization of electric vehicles may change the way people travel transportation and energy use patterns in the electric vehicle development process, its market positioning as technology development may be constantly changing, so the different stages of technology, electric cars need to use specific ways to achieve commercial operation of the market Inspiron 1501 Inspiron 6400 battery Inspiron E1505 battery .
A lithium battery company officials said, the industrialization of the final guidance from the commercial, industrial integration of resources needed to guide business operations. According to him, the current domestic electric car industry chain, many companies are seeking deeper cooperation.
For the power lithium battery technology, Xiao Chengwei that China’s lithium battery performance level in the current level increased by 30% or more is no problem. “By enhancing the performance and battery raw materials, their design, process control, integration and other aspects of the battery pack can achieve this upgrade.”
Huang Xuejie that by 2015, electric vehicle batteries will abide by the basic iron phosphate lithium battery technology based course. “By 2015, battery life can reach 10 years, and cost competitive. To 2020, it will certainly replace the lithium iron phosphate cathode material there is expected when the battery specific energy will be doubled, the cost is only half of the . “According to him, there are already a kind of lithium manganese oxide-based layered oxides, the specific capacity greater than 250 mAh / gram. Next-generation battery materials technology is expected to achieve this upgrade.
Winner will be C1295 Inspiron 500m Inspiron 510m battery
For the current domestic power lithium battery industry, the existence of blind investment and redundant construction, experts mixed views. Huang Yu-yuan that the more serious phenomenon. Some parts of the industry, regardless of the basis and conditions of their own, have no maturity of the technology of the scientific assessment of the blind decision-making, leading to a large number of low-end, technology premature battery Xiangmu launched. This not only brings great risks to investors, but also disrupted power battery market has just started on the development of China’s battery industry is very negative.
Xiaocheng Wei believes that, from the industry point of view, the more engaged in the business of promoting the greater development of the industry, upgrading of technology, industrial scale are very helpful. Some companies do not rule out low-level redundant construction, but the state can develop policies and measures to guide and regulate the industry to develop healthily Inspiron 600m battery .
“Everything always have a balanced development, then in the development of self-balance or to the external environment to balanced development. Current power lithium battery industry is unbalanced on the stage of development, domestic and foreign enterprises are optimistic about the market, therefore, not exist to avoid too high expectations, the phenomenon of excessive investment, which requires businesses and state take the time to understand and adjust. “Wei Navy that.
In Huang Xuejie view, an early stage of development the industry is the pack and play, rushed into. At this stage, the government can appropriate guidance, information disclosure, while experts should also be held accountable. Local governments should not blindly be launched, should thoroughly understand the policy, according to the specific situation, and so realistic analysis. Huang Xuejie that the winner will be ,5-8 years will see the outcome.
Promise for the development of nickel-hydrogen batteries for a future Latitude D500 battery Latitude D505 battery
“Lithium-ion battery power battery development has become the mainstream, but that does not mean that other routes have been excluded. All have their applications battery target market, each type of battery will be a corresponding development, but the momentum of development and suffered lack of concern about the state’s efforts to support a different. “Recently, the National 863 Program of major energy-saving and new energy vehicles overall project Power Group Chemistry and Physics Laboratory of the battery duty expert Xiaocheng Wei told reporters.
As a useful complement to one of the lithium-ion batteries, include nickel-hydrogen batteries. In fact, in the field of automotive battery, nickel hydrogen batteries and lithium-ion battery technology long struggle, but who soon get more preferential policies will undoubtedly affect their development in the industrial chain. In this round of game, lithium-ion batteries clearly gained the upper hand.
Policy “Changing Faces Latitude D510 battery ”
This year in June, the four ministries jointly issued “on the purchase of new energy vehicles to carry out subsidies for private pilot’s notice”, on the plug-in hybrid electric passenger cars and passenger cars for one-time subsidy. Subsidies to the energy standards established under the battery pack on the support conditions to meet the new energy vehicles, according to 3000 yuan / kwh subsidies. Plug-in hybrid vehicle the maximum subsidy per 50,000 yuan, the highest of pure electric passenger vehicles per 60,000 yuan subsidy. Non-plug-in hybrid vehicles are included in “projects that benefit the energy-saving products”, according to the standard per 3,000 for one-time fixed subsidy.
From the subsidy standards for the plug-in hybrid electric passenger cars and passenger cars lithium-ion batteries have been more preferential policies, and in the non-plug-in hybrid electric vehicle and take great advantage market share of NiMH batteries, 3,000 yuan of subsidies to the standard is too insufficient to cover its costs.
Nickel-hydrogen battery business executives on policy, “Changing Faces” very depressed. Last year in June, the Department of Industry and Information Technology announced the “new energy automobile manufacturing companies and product access management rules” will be based on nickel-hydrogen battery technology, hybrid vehicles are classified as mature products, allowing use in nationwide sales, while lithium-based technology in the development of hybrid vehicle ownership of only the approved area, scope, terms and conditions, sales, use Latitude D520 battery Latitude D600 battery .
After the introduction of the policy, Ni-MH battery manufacturer of Metal Mesh. Over the past year, Keli far, Chunlan Group, the torch high, Hunan Shenzhou, Kane shares are on the nickel-metal hydride batteries into great. After one year, held in Beijing in 2010, the Sixth Beijing International pure electric vehicles, hybrid electric cum clean energy vehicles and parts exhibition, exhibition of few nickel-hydrogen batteries, nickel hydrogen batteries seem to be into the marginized.
Industry Ideas
NiMH batteries will face what the future prospects?
Xiao Chengwei that in hybrid vehicles, nickel metal hydride batteries in the next five years to maintain an advantage and will dominate a larger market share. The lithium-ion batteries used in hybrid cars will gradually raise the share.
Institute of Physics, Chinese Academy of Sciences researcher Huang Xuejie that China’s nickel-hydrogen battery technology is not mature industry, there is no mass production capacity. If you now go to the introduction of advanced equipment, so the time has late, too big a price to pay, how to develop the need for a comprehensive thought.
But at the same time, China is rich in nickel metal hydride battery raw materials. China Automobile Industry Association Executive Vice President and Director General Yang Zeng said: “China has Fengfu of rare earth materials, but our process Wufa be processed into a car on rare earth materials used Yongci materials, we can only export of rare earth, import Yong Magnetic Materials. “Therefore, how to maximize resources for many of the industry thought Latitude D610 battery .
Huang Xuejie suggested domestic enterprises NiMH batteries should further enhance the level of key materials, for integration into the industrial chain. “If a large number of rare earth resources into car battery materials, there are still great opportunities in China. Such as Keli much raw material is nickel metal hydride batteries the largest manufacturer of nickel foam, nickel metal hydride battery if domestic enterprises, as the company into the same chain, although not achieve the main role, but can play a key role in material supply, as valuable. ”
Beijing Nonferrous Metal Research Institute, Senior Engineer Energy Materials and Technology Research Institute, Dr Wei Navy to reporters about the nickel-hydrogen battery, a new application areas - replacement batteries, he thinks this will be the future of nickel-hydrogen batteries as a major development direction. “Ni-MH battery in the emerging application areas such as replacing disposable batteries of advantage has showed so strong development momentum.” According to him, Japan’s Sanyo Gongsizhendui consumer markets developed a Dizi Ni-MH battery discharge rates , after 1 year storage capacity retention rate of 85% capacity retention rate after two years 75%, completely breaking the traditional nickel metal hydride battery storage performance difference (ie self-discharge rate and storage capacity retention after 1 year was 50% Two years later, the basic capacity to zero) the disadvantages of the traditional Ni-MH battery into the era of new applications, is expected to replace disposable batteries. A low self-discharge rate of NiMH battery is equivalent to a one-time 1000-2000 Day, and the larger, higher power, fully green, dry batteries PC764 Latitude D620 battery can significantly reduce the one-time application, energy conservation, protecting the environment.
It is understood that, in 2007 and 2008, low self-discharge rate of Sanyo Ni-MH battery shipments were 25 million and 30 million, and increased year by year. As of the end of October 2009, the company’s low self-discharge rate of Ni-MH battery shipments has accumulated more than 100 million. Wei Navy told reporters that some domestic universities, research institutes have also been doing research in this area, but not excellent, lots of low self-discharge rate and good stability NiMH battery anode material, domestic battery and low self-discharge Battery compared with foreign products, there is a wide gap.
Suggestions of experts
Battery new path: two four-wheel drive
Reporter Dan reports on
The battery industry, Chinese Academy of Sciences Institute of Physics Fellow Huang Xuejie proposed a new path, that is, “with two wheels to carry four wheels Latitude D820 battery Latitude D830 battery .”
Huang Xuejie reporter cited an example, NEC is the Nissan electric car hear the wind (LEAF) battery supplier, but it is also Europe’s largest electric bike batteries. The electric bicycle battery batteries manufacturing, design and electric car batteries and no difference. “NEC honed in the electric bike market for 8 years, forming a high-volume production ability and relevant experience gained, and now Nissan will be able to supply electric car batteries. Chinese enterprises can also take this path.” Huang Xuejie said.
At home, are practicing this line in Suzhou Star Constant Power Co., Ltd. from the early days of clear direction from the bike battery car battery development goals. According to reports, the company’s electric bike batteries have been in Europe market compete with Japanese battery, occupied 20% market share in Europe, and its main equipment are independent research and development, product consistency have improved significantly. Last year, started Suzhou Star constant supply of automotive battery business. Shanghai Expo has 173 new energy vehicles using the company’s lithium-ion battery. The reporters also learned that this year in January, Suzhou and Shanghai Star Constant Power Systems fuel cell car joint venture build a car battery Co., Ltd. Shanghai Heng Activity will be mainly for new energy vehicles in hybrid vehicles, electric vehicle production as its key components of Li-ion battery power system products, and automobile enterprises to provide new energy matching products and technical services Y9943 , Inspiron 630m battery .
Suzhou Star either NEC or constant, it seems to describe a people “two wheels driving four wheels” of the beautiful picture. Accordingly, the choice in electric vehicles, many of the industry have unanimously told reporters that China should give priority to the development of miniature, low-speed pure electric vehicles.
China Electrotechnical Society, honorary chairman of Zhouhe Liang said China’s industrialization in the electric bike has been to go ahead in the world, on the lower reaches of the formation of a complete industrial chain, technology has matured, these are low-speed electric vehicles for the development of laying a good foundation Inspiron 640m battery .
“China in the development of electric vehicles should be two grasping: a grasp urban public transportation, sanitation trucks, increased application difficulty and technological upgrading; a grasp electric two-wheelers, low-speed electric cars, access, security, driver’s license, insurance, etc. make all aspects of specification, guide enterprises to use lithium batteries and give them subsidies. the first, if arrested, will promote industrial development play a bigger role. “Huang Xuejie that push forward the two wheels, 3-5 years My battery level will be greatly improved.
“Lithium-ion battery electric bicycle company for two years even if all can not guarantee life, wanted to make the life of 8 years of electric vehicles is not possible.” Huang Xuejie that a man does not pay attention to details, the current per-watt electric bicycle battery when the price of 2.5-3 yuan, which is the auto maker hopes to get the price. “Vehicle Power Battery Factory are now losing money, while the electric bicycle battery can make money. So, why not to start from the low-end? Only after sufficient accumulation, before ushering in the improvement of quality.”
All sound
863 plans major energy efficiency projects and new energy vehicles in general chemistry and physics Power Group Key Laboratory of Cell Expert Xiao Chengwei responsibility: the second half is expected to introduce energy-saving and new energy development plan in the automobile industry, will cover a variety of technologies, including hybrid , fuel cells, electric cars, and charging facilities, technical standards. Policy guidance will certainly be emphasized, will focus on pure electric vehicles as a strategy to support, but not that only supports one aspect, the other not to develop Inspiron E1405 battery .
Institute of Physics, Chinese Academy of Sciences researcher Huang Xuejie: Currently, lithium-ion battery is only a small part of the recovery, and the focus electrode material recovery of valuable metals. According to Li-ion battery development and future environmental requirements, large batteries need to take the step separation of access and standards of cleaning machinery parts Huishou routes to achieve efficient use of resources and reduce environmental pollution and to be prepared before being made active.
College of Chemistry and Molecular Huang Yu-yuan: From the international point of view, Ni-MH battery cells from the gradual transition to lithium ion batteries, lithium batteries power our country to go directly to the line would be more appropriately. The current policy orientation is also evident, the government will subsidize the focus on plug-in hybrid and pure electric vehicles, electric vehicle industry, suggest the Government to encourage the development by leaps and bounds, skip the stage of ordinary hybrid Studio 14 battery Studio 1435 battery .
Beijing Nonferrous Metal Research Institute Energy Materials and Technology Research Institute senior Wei Navy: future, power battery market will present a hundred flowers blooming, have done their best picture. Nickel-hydrogen batteries for many years to mature as a market based commercial operations in the next 5 years, hybrid car market will continue to occupy an important position, while the lithium-ion batteries in plug-in hybrid and electric car market dominated . In addition, there will be some new battery technology was born.
