Recently, the "Energy Conservation and New Energy Vehicle Technology Roadmap" announced by the Chinese Society of Automotive Engineers has drawn a blueprint for the development of China's power battery technology. The roadmap proposes that by 2020, the specific energy of pure electric vehicle power battery cells will reach 350Wh / kg, by 2025 it will reach 400Wh / kg, and by 2030 it will reach 500W h / kg; in the near to medium term, the existing system lithium-ion power will be optimized. At the same time that battery technology meets the needs of large-scale development of new energy vehicles, it focuses on the development of new lithium-ion power batteries, improves its key technologies such as safety, consistency, and life, and simultaneously carries out forward-looking research and development of new system power batteries; While continuously optimizing and upgrading new lithium-ion power batteries, we focus on the research and development of new system power batteries, significantly improving energy density, significantly reducing costs, and realizing the practical and large-scale application of new system power batteries.

It can be seen that for a long time to come, lithium-ion batteries will still be the mainstream products of power batteries. Lithium-ion batteries have high specific energy, long cycle life, environmentally friendly, and can have both good energy density and power density. The advantage is that the power battery with the best comprehensive performance has been widely used in various electric vehicles.

From the perspective of industrial development, currently world-renowned manufacturers of electric vehicle power batteries, including Japan's Panasonic, Vehicle Energy Supply Corporation (AESC), South Korea's LG Chemical, and Samsung SDI, are actively promoting the research and development of high-specific-energy power lithium-ion batteries .

Development trend of key materials for lithium-ion power batteries. Lithium-ion batteries use high-potential lithium-containing compounds that reversibly store and release lithium ions as positive electrodes, low-potential materials that reversibly insert and desorb lithium ions as negative electrodes, an electronic insulating layer that can conduct lithium ions as a separator, and lithium salts dissolved in organic solvents as Electrolyte.
