How to develop a safe power lithium-ion battery? How to enhance the safety of battery cells, modules, and battery systems (including management systems), the reliability and life of the operating environment? How to break through the safety, consistency and reliability of power batteries and systems Key technologies such as sex and low cost?

　　From the restricted purchase of fuel vehicles to the haze panic caused by Chai Jing "under the dome", from the promotion of new energy vehicles to the problem of charging piles, from the development of small electric vehicles to a rational view of the development of pure electric vehicles. Under the trend of vigorously developing new energy vehicles, especially under the development situation of hybrid electric vehicles tending to pure electric vehicles. Batteries are particularly important as the most critical energy storage component of electric vehicles.

　　Chen Qingquan, the father of Asian electric vehicles, he proposed to establish the World Electric Vehicle Association in 1988, and has been committed to promoting electric vehicles worldwide for many years. In recent years, he has spent two months doing research in Germany each year. Collaborative innovation plays a very important role in German technological and industrial innovation. From large companies to small and medium-sized enterprises, German companies compete fiercely in innovation and product quality improvement, but they never have to suppress each other with price wars. German companies are closely connected and exchange what is needed. They call this close communication an elite cluster, sharing the dividends of innovation and technology. Especially in Germany's most competitive chemical, automotive, electronic equipment and engineering fields, they will not dismantle each other, but will work together.

　　Most of the research and development of power batteries in our country adopt the method of independent research and development of enterprises, and the competition is fierce, not to mention close contact and cooperation. At the 2015 Shanghai Auto Show, Volkswagen has successively produced 15 new energy vehicles in China, but the two battery suppliers that have been identified are South Korea’s Samsung and LG, and they have no chance with Chinese companies. This case fully reflects the challenges facing my country's power batteries. In order to enable the development of power and energy storage technology to meet the application and market needs of new energy vehicles, new energy and smart grids. There is an urgent need for business cooperation and joint innovation between government and enterprises. It is more necessary to give play to the guiding role of the government, organize superior forces, concentrate on tackling key problems, promote key original innovations, solve bottleneck technologies, and obtain intellectual property rights in order to be able to be in a competitive position.

　　At present, China is currently facing environmental problems that are not optimistic, and the desire to develop electric vehicles is more urgent than any other country. The research and development of electric vehicles and the research and development of power battery systems have a long way to go.
