Chen Jun: In the next one or two years, electric cars will be able to run more than 1,000 kilometers on a single charge. According to CCTV, this morning (March 8), the second "representatives' channel" of the 14th National People's Congress was held in the Great Hall of the People. Chen Jun, a representative of the National People's Congress, vice president of Nankai University, and a academician of the Chinese Academy of Sciences, accepted an interview. Chen Jun introduced that he and his team have developed a solid-state battery with an energy density of 400 watt-hours per kilogram, which is more than 30% higher than the most advanced 300 watt-hours per kilogram lithium-ion batteries currently on the market. In the next one to two years, they aim to break through the development of solid-state batteries with an energy density of 600 watt-hours per kilogram, which will enable electric cars to run over 1,000 kilometers on a single charge.
