China to release solid-state battery standards in July

China is set to release its solid-state battery standards in July, Car News China reports, citing Mydrivers, with China Automotive Technology and Research Centre‘s (CATARC) chief scientist sharing that solid-state battery mass production is expected to start next year.

Here’s the timeline. A draft was reportedly completed in December 2025 and the public consultation period runs up to end-February, throughout which CATARC will carry out verification tests. The new standards are expected to be completely reviewed and approved by April before being released in July, and will draw lines between liquid-, semi-solid- and fully-solid-state batteries.

Solid-state batteries are thermally stable and very energy-dense – they can achieve 300-400 Wh/kg, or about twice what a typical lithium iron phosphate (LFP) pack can muster. They use a solid block made of either polymer, oxides or sulfides instead of a liquid electrolyte to shuttle charge-carrying ions between the anode and cathode.

The MG4 Anxin Edition is the first production car with a semi-solid state battery, while the Verge TS Pro e-bike is the first production vehicle with an all-solid state battery. Geely’s also developing an all-solid state battery; we should hear more from Hangzhou later this year. Others working on the technology (or have explored it in the past) include BYD, Chery, GAC, Dongfeng, FAW, Toyota, Honda, Nissan, Mercedes, BMW, Ford, Nio, Hyundai and VinFast.
