Question 1: According to the planning of the national power battery road map, the 20020 lithium-ion battery unit energy density is 350Wh / kg in 2020. It is already 2020, can you disclose whether this goal is already realized? And, what if you want to further increase the energy density of the battery, what is the right route?Inssenstrual answer: In order to understand the National New Energy Car Special Power Battery R & D situation during the 13th Five-Year Plan, the Ministry of Science and Technology High Technology Center has undertakes the four units of high-performance battery R & D projects in 2019 (CATL, Qi Shen, Guoxuan, China AV The lithium ion power battery sample developed has been commissioned by the third party. From the current test results, the power battery is more than 300-310WH / kg, and some of the samples of some units have reached more than 1200 times. In terms of energy than energy, there is still a certain gap between 350Wh / kg, but at the end of 2020, 330Wh / kg should say that there is no difficulty.
