Li Auto plans to introduce solid-state batteries for limited vehicle deployment by 2027 or 2028. According to company senior director Liu Zhimin, achieving mature mass production for automotive use will require approximately five more years due to ongoing challenges with battery lifespan, charging performance, and production costs.

The company has already validated solid-state prototypes in its Livis smart glasses, launched in December 2025. This research is part of a broader strategy to expand in-house battery development, which began in 2020 and currently covers 5C cells, battery packs, and management systems.

Production is handled through a 2025 joint venture with Sunwoda, where both firms hold equal stakes. Furthermore, Li Auto is set to acquire an 8.79 percent stake in Sunwoda Electric Vehicle Battery, becoming its second-largest shareholder to deepen their manufacturing partnership.

Other industry players are also targeting 2027 for solid-state milestones. Chery Auto plans to begin vehicle validation in 2027, while CATL aims for small-batch production readiness by the same year. CATL currently ranks its own solid-state technology at level 4 on a 9-point scale.
