China to release solid-state battery standard in July 2026

China will release the first solid-state battery standard in July 2026 as the mass production of such packs is about to start next year, the chief scientist of the China Automotive Technology and Research Center (CATARC) shared.

It was reported that the draft of the “Solid-state batteries for electric vehicles Part 1: terminology and Classification” GB/T standard was completed in December 2025, with the comment period ending on February 28, 2026. According to Mydrivers, CATARC will organize verification tests in February 2026 to further refine test methods and confirm judgment indicators.

The new standard is expected to be completely reviewed and approved in April 2026. The official release date is reportedly scheduled for July this year. These standards will focus on basic information about solid-state batteries. It includes clarifying the definitions of terms such as liquid batteries, solid-liquid batteries (semi-solid batteries), and all-solid-state batteries.

More about the standard

It is expected that the following parts of the standard will be released in the future. They will include some guidelines and requirements for the solid-state electrolyte and other elements. A lot of Chinese automakers and battery manufacturers actively develop such battery packs have some advantages. They include higher energy density and flame resistance.

Solid-state batteries boast an energy density of over 300 Wh/kg. The latest Dongfeng-developed battery is a good example. It began testing of the battery with a density of 350 Wh/kg installed on the eπ 007 electric sedan. The automaker shared that this battery will allow the car to run over 1,000 km on a single charge with a 72% energy retention rate at temperatures as low as -30 °C.

Previously, Chinese scientists announced they successfully developed a silicon nanowire anode with a “breathable” structure for solid-state batteries. It provides battery packs with enhanced safety, higher energy density, and superior cycle performance. According to previous reports, BYD, Geely, Chery, GAC, Dongfeng, FAW, and other automakers will start installation trials of all-solid-state batteries next year.
