固态电池进展

Group 1 - The performance of the battery shows a cycle life of 300-400 times at 90% SOC, and it can achieve commercial purposes at 80% SOC, with an energy density of 350Wh/kg [1] - The material selection includes sulfide-based electrolytes, high nickel cathodes, and artificial graphite combined with silicon-carbon anodes, with a small portion using no anode technology [1] - The manufacturing process utilizes isostatic pressing equipment to address solid-solid interface issues, currently employing wet processing with potential future adoption of dry processing [5] Group 2 - The pilot production line has been completed [5]
