Lithium power battery long way to go
National support policies will continue to follow up: the new energy vehicles has risen to national strategies, and continuously push forward is not in doubt, follow-up will also have the support of the policy have been put forward “New Energy Auto Industry Development Plan” prepared to consider the State Department reported early in July, to wait until after the completion of the preparatory work will be implemented, “planning” mainly from the research and development production, marketing, service and recycling and other links start to develop the corresponding industrial policy, Inspiron 1526 battery fiscal policy, tax policy, investment and financing policies. On the current state of technology, the lithium battery is the best choice for car, all face forward is very positive lithium.
Can reduce the production cost of a lithium battery to run the main obstacles to business: lithium battery under current technology, cost and safety has not yet been sufficient to support live data. The use of lithium iron phosphate is considered for solving the security, the best cycle life of a cathode material, after mixing elements Meng Meng lithium iron phosphate material will further improve the battery’s specific energy, specific power, if the anode material lithium titanate can successfully replace the existing graphite would further address the safety and cycle life problems, the progress of the electrolyte membrane, and also will make further contributions. Over time, Inspiron 1521 battery technological progress, safety and cycle life, the cost will be greatly improved.
LEV (Light Electric Vehicle) or lithium power battery business of promoting the vanguard: The domestic electric bike market about the size of more than 100 million, and the rate of annual increase of 20 million, of which 95% are using lead-acid battery, lithium battery to promote commercial use of a more realistic approach is to increase the lithium battery in the LEV, that is, electric bicycles, electric motorcycles, the use of small electric car, made certain industrial scale and lower costs . To manufacture the electric cars that replace the traditional internal combustion vehicles, then the lithium RN873 to meet the cost of 1 yuan / WH, battery cycle life of 2,000 (or 15 years), and the present distance of the target also some gaps. China’s goal is to 2012 to achieve specific energy lithium battery 120WH/KG, specific power 1000W/KG, 2,000 cycle life, cost 2 yuan / WH; to 2020, the lithium battery than the energy to do 200WH/KG than the power 1500W/KG, 3000 cycle life, cost 1 yuan / WH.
18650 cylindrical core VS large capacity lithium batteries square Choice: Domestic including BYD, universal and so were powered by single battery capacity 10AH batteries into the square group, the advantage of group power required will significantly reduce the number of cores, but this square batteries industry data are inadequate, difficult to ensure consistency, group after the poor cycle life, high cost; abroad, including the BMW is used in such a cylindrical single-18650 body of the battery capacity of around 2AH batteries, such batteries is the general consumer lithium batteries, Chanye of very experienced and batteries Y6142 , KD186 are quite consistent, low cost, Danshi need more sophisticated the battery management system to control After the battery pack into the group. For square or cylindrical which is more appropriate is inconclusive, we tendentious view is perhaps the 18650 cylindrical batteries larger capacity batteries are commercially square the successful operation of the actual conditions, with greater capacity, square type of technological progress and the cost of batteries down, the future may be dominant.
Lithium battery storage areas or open a broad new world: the market is more concerned about the use of the battery as a power, in fact, the use of energy storage is a broad field of earth. Energy storage battery as an integral part of the smart grid can be applied not only save wind, solar and other energy forms new energy instability can also play the role of load shifting. May adopt a “cascading” in the form of advance, the storage battery due to its storage is static, lower demand for consistency, even after retirement battery can continue to serve the energy storage. However, the lithium Latitude D620 battery on the uses of large-scale commercialization of Li-ion battery recycling is still a problem to be solved, this point is not current technology maturity, such as lead-acid battery recycling.
