BYD's Solid-State Battery Roadmap: Pilot Production Achieved, Mass Production Post-2030
2025-02-23
BYD's battery business CTO, Sun Huajun, revealed that the company has already produced 20Ah and 60Ah solid-state battery cells on its pilot production line in 2024. Mass demonstration is expected around 2027, but large-scale mass production is likely only after 2030. BYD is focusing on sulfide electrolytes due to cost and process stability advantages. Similar to CATL, BYD anticipates solid-state batteries will initially be used in high-end models, complementing their existing LFP batteries.
