Research and development of power battery is quantity not quality breakthrough into a critical stage

On March 21, the day can power released 2015 annual performance report, its new energy vehicle power battery sales rose 209% year-on-year, for overweight this market, the company will be in this year will be the battery capacity expansion to 2. 25GWH。 The porch high-tech, byd, such as enterprises, are announced this year's large-scale expansion plan. A head of battery companies had previously told the 'daily economic news' reporter, a rough calculation, 1 GWH power battery can satisfy the assembly of 40000 new energy cars. In this case, the battery enterprises large-scale expansion is considered, is expected to solve the problem of insufficient power battery capacity. After the Beijing auto, jac, saic and other new energy automobile production enterprises responsible for per capita to the 'daily economic news' reporter said, as the key components, power battery supply has begun to limit its new energy vehicle production. Complement to gradually, however, even if the battery number, but the power battery technology and quality, develop new energy vehicles industry is still one of the biggest constraints. The reporter understands, during the '315' complaints about the new energy automobile consumption, the range does not accord with propaganda, charging power does not accord with propaganda, battery failure off electricity three big problem is becoming a hot spot of complaints seriously, and these problems are related to the battery. 'at present, the use of cars power battery technology is old, not a revolutionary new battery. Saic 'head of a research and development of new energy vehicles told the 'daily economic news' reporter,' now, the energy density of the power battery technology is still very limited. 'we have learned, at present, the car power battery mainly including lead-acid battery, manganese lithium iron phosphate batteries, lithium iron phosphate batteries, cobalt acid lithium batteries and ternary polymer lithium battery, etc. In the present mainstream power battery technology, the main way of storage is single and increase the quantity of batteries. 'cell number can reduce security. 'will power battery as the main business of the micro macro power of the company's chief scientist Dr Yvonne lau to the 'daily economic news' reporter said,' the short circuit can increase the probability of causing thermal runaway, simply is to increase the probability of spontaneous combustion. '' in accordance with the industry the highest standards of 18650 batteries PPM to calculate the rate of quality control, each production one million batteries, there will be two quality problems. 'micro macro dynamic Wu Yang chief executive, said that is to say, each sold 100000 cars, a risk will have 1600 battery. In the life, safety, all under the condition of insufficient, the industry generally expected power battery new technology breakthrough. At the end of February, the ministry of industry and information minister MiaoWei was in the State Council Information Office conference, power battery technology determines the performance, quality, safety and so on various aspects of the success or failure. To promote the development of the power battery technology, the ministry of industry and joint 9 companies, has invested 500 million yuan to build power battery or power battery research institute development platform. Under this background, the power will explore new technology, is widely regarded as an opportunity, and more enterprises to participate in and will accelerate the exploration process. Lithium battery USES the first-line brand power battery at home and abroad, but high rate discharge, safe and stable performance. Using automatic sorting machine, spot welding and testing equipment. Guarantee the quality of products in each group.
