Solid-state Battery

Svolt has completed development of its first-generation semi-solid-state square battery cells with an energy density of 270 Wh/kg.

These solid-state batteries feature an energy density of 350 Wh/kg, and Dongfeng has already put a 0.2 GWh pilot line into operation.

"Semi-solid-state batteries" will be named "solid-liquid batteries" in China to prevent public confusion with solid-state batteries, according to a local media report.

Sunwoda plans to complete a 0.2 GWh pilot production line for solid-state battery cells by year-end.

The all-solid-state battery cells achieve an energy density of up to 300 Wh/kg or 700 Wh/L.

The semi-solid-state batteries will be supplied to BMW Mini's next-generation models, with mass production planned for 2027.

Gotion's Gemstone all-solid-state battery has been loaded into vehicles and tested on the road.

Changan aims to validate solid-state batteries in vehicles by 2026, and move forward with gradual mass production by 2027.

Voyah's third-generation solid-state batteries will maintain the energy density of 300 Wh/kg, but increase the charging multiplier to 3 to 5 C.

Large-scale adoption of all-solid-state batteries may not happen until after 2030, BYD's battery business CTO said.
