Recently, the first batch of 50 sets equipped with solid-state flexible separator batteries fengshen E70 as a demonstration operation vehicle in Xinyu City, Jiangxi Province, it is understood that the batch of vehicles equipped with solid-state flexible separator technology batteries developed by Dongfeng Motor and Ganfeng Lithium. The first batch of 50 E70s equipped with this type of battery will be put into operation in Jiangxi, Guangzhou, Zhejiang and Jiangsu provinces.
The solid-state flexible separator battery developed by Dongfeng Motor in cooperation with Ganfeng Lithium Industry, according to the official introduction, its diaphragm is all solid state and the electrolyte is semi-solid, which is closer to the semi-solid state battery previously released by Weilai and prepared for mass production by Beijing Weilan New Energy.
Although it is not a solid-state battery in the strict sense, the technical level of solid-state flexible separator batteries is also in the forefront at home and abroad, compared with lithium batteries with pure liquid electrolytes, semi-solid-state batteries have the advantages of higher energy density, thinner, more flexible and safer. The real sense of solid-state batteries (electrolyte completely solid-state) is currently not commercialized in the passenger car market due to cost and some technical problems.
According to the official introduction, the solid-state flexible separator battery cell has passed rigorous tests such as puncture and 50% extrusion deformation, with a discharge temperature of up to 60 °C and a hot box of 180 °C without abnormality; the solid-state battery module adopts aluminum alloy frame and high-precision seam laser welding technology to reduce redundant structures and group efficiency of up to 86%.
