# Solid-state and semi-solid-state batteries: China accelerates, CATL targets 2027 > In early November 2026, several Chinese automakers accelerated in-house battery development, particularly semi-solid and solid-state, while BYD's Blade battery plant in Shaanxi reached full production. This drive aims to reduce reliance on major cell manufacturers such as CATL, while maintaining massive contracts and prepayments; CATL hopes for a small production run of solid-state batteries in 2027. Worldwide, articles review the maturity of solid-state batteries and compare Chinese programs with Toyota's, around a target of approximately 1,000 km of range.
