MIIT Releases Solid-State Battery Standards: 400Wh/kg Target by 2028

On May 27, 2026, China's MIIT released the solid-state battery standards research guide, outlining a three-phase roadmap from 2026 to 2030: basic research → engineering validation → commercialization. Target energy density: 400Wh/kg (2028) and 500Wh/kg (2030). Semi-solid-state batteries are already in mass production, while all-solid-state batteries are expected to enter small-batch vehicle installation in 2028. Chinese companies hold 65% of global patents.
