- All-solid-state EV batteries are set for market launch in 2027, with companies like BYD and SAIC Motor leading the charge.
- Key Chinese automakers, including SAIC, BYD, Changan, Chery, and Dongfeng, are developing all-solid-state batteries with energy densities around 400 Wh/kg, enabling ranges over 1,000 km.
- Solid-state batteries offer higher energy density, faster charging, improved safety due to reduced or eliminated liquid electrolytes, and longer driving ranges.
- BYD plans to start limited production of sulfide-based all-solid-state batteries in 2027, scaling to mass production by 2030, initially for high-end models.
- SAIC's all-solid-state batteries aim for energy density above 400 Wh/kg, targeting over 1,000 km range, with semi-solid-state versions already reducing combustion risks.
- Global interest extends beyond China, with companies like Mercedes testing solid-state batteries from startups like Factorial Energy for enhanced performance.
- Solid-state batteries complement rather than replace liquid lithium-ion batteries, supporting a broader transition to electric vehicles alongside other technologies like sodium-ion batteries.
