Toyota

Type: Company (Automotive + Battery — Japan's Largest Automaker)

Toyota is advancing solid-state batteries through an oxide/lithium-sulphide electrolyte pathway, in partnership with Sumitomo Mining and Idemitsu Kosan for material supply. In October 2025, Toyota received Japan's METI production certification — a regulatory milestone that signals readiness for commercial-scale manufacturing. Mass production of solid-state cells is slated for 2026, with vehicle deployment in a Lexus flagship targeted for 2027.

Solid-State Battery Program

• Regulatory milestone: METI (Ministry of Economy, Trade and Industry) production certification — October 2025
• Mass production: Beginning 2026
• Vehicle integration: Lexus flagship 2027
• Performance target: 1,200 km range on 10-minute charging
• Electrolyte pathway: Lithium sulphide (oxide-based approach)
• Material partners: Sumitomo Mining (lithium), Idemitsu Kosan (lithium sulphide)

Competitive Position

Toyota's METI certification sets it apart from CATL and Samsung SDI as the only player with formal government production approval as of late 2025. The 1,200 km / 10-minute claim, if validated at production scale, would surpass current premium EV benchmarks. The Lexus deployment (vs. Toyota mass-market) suggests initial commercial volumes will be premium/limited before broader rollout.
