[Solid-State Batteries: A Critical Moment in 2027] 2027 will be a critical period for industrialisation:
Automaker plans: BYD plans to launch demonstration loading of all-solid-state batteries in 2027, CATL is expected to commence small-scale production in the same year, and Changan Automobile plans to mass-produce products with a capacity of 400Wh/kg.
Technological breakthroughs: The bottleneck in the mass production of sulphide electrolytes has been overcome (by Regu New Materials), the team from the Chinese Academy of Sciences has solved the problem of short-circuit causes, and standardisation documents have been issued one after another.
Capacity construction: Beijing Weilan has already commenced mass production of semi-solid-state batteries with a capacity of 360Wh/kg, and Gotion High-tech has established a 0.2GWh pilot production line for all-solid-state batteries.
