- BYD plans limited production of sulfide‑based all‑solid‑state batteries in 2027 and mass production by 2030, starting with its high‑end sub‑brands (Denza, Yangwang, Feng Chang Bao).
- SAIC Motor aims to mass‑produce all‑solid‑state EV batteries in 2027 after prototype testing with its “Guangqi” battery, claiming >400 Wh/kg energy density and >1,000 km range.
- Changan Automobile will fit its “Golden Bell” all‑solid‑state battery into vehicle prototypes by year‑end and target mass production in 2027, touting 400 Wh/kg energy density and >1,500 km range.
- Chery announced an all‑solid‑state battery delivering >1,500 km range with 400 Wh/kg energy density.
- Dongfeng Motors is testing a 350 Wh/kg all‑solid‑state battery in prototype EVs, promising >1,000 km range.
Why it matters: The 2027 rollout gives Chinese makers a head start on high‑energy‑density EVs, opening premium market share while squeezing rivals still stuck with liquid‑ion tech and forcing battery suppliers to shift production.
