China Enacts Strict Solid-State Cell Standards (July 1, 2026)

Solid State Battery Market 2025 to 2032: Commercialization Trajectory and the Electrification of Energy Storage →

What Changed

China has implemented a landmark national standard requiring cells to undergo a rigorous 120°C vacuum chamber test for 6 hours to verify commercial readiness. To earn the official 'all-solid-state' designation, the remaining liquid electrolyte must be under 5% of the total cell weight. This regulation aims to combat unverified commercial claims and enforce technical transparency.
