China News Service, Beijing, March 8 (Reporter Jiang Feibo) On March 8, Chen Jun, a representative of the National People's Congress and an academician of the Chinese Academy of Sciences, said at the "Delegates Channel" in the second session of the second session of the 14th National People's Congress that in the next one to two years The research and development of solid-state batteries with a capacity of 600 watt-hours per kilogram will be exceeded by the year. Electric vehicles can run more than 1,000 kilometers on a single charge.
Chen Jun has done research in the battery field for more than 30 years.
He mentioned that current electric vehicles do not run fast enough and charge fast enough, especially in cold weather, they are prone to "falling asleep". These phenomena are actually related to the battery, so research on better-performing and safer vehicles is needed. Batteries are a major technological issue both in the electric vehicle industry and in the energy storage field.
On March 8, the second "Representative Channel" concentrated interview event of the Second Session of the 14th National People's Congress was held in the Great Hall of the People in Beijing.

At present, solid-state batteries are the focus of research and development in various countries. Once industrialized, they will change the existing electric vehicle industry pattern and open up emerging markets such as electric aviation.
Chen Jun revealed that his team actively undertakes major national research plans and key R&D projects, and collaborates with Beijing's scientific and technological innovation superior units to jointly tackle key problems. It has developed a new solid-state battery sample of 400 watt hours per kilogram, which is more advanced than the 300 watt hour currently on the market. The energy density of lithium-ion batteries per kilogram exceeds 30%.
In the next one to two years, solid-state batteries with a capacity of 600 watt-hours per kilogram will be developed so that electric vehicles can run more than 1,000 kilometers on a single charge.
At the same time, fast charging, low-temperature performance and safety performance must also be greatly improved.
"This is a leading technological change in the world. We are also actively seizing the commanding heights of the future development of power batteries and electric vehicles." Chen Jun said that industrial innovation is an important carrier and landing point of technological innovation, and the two mutually promote each other. Integration and complementation must be promoted as one. In the future, the team must organically connect the innovation chain, industrial chain and talent chain of batteries to accelerate the formation of new productive forces and promote high-quality development.
