China is preparing to introduce its first solid-state battery standard in July 2026, with mass industrial production of such batteries expected to begin next year, according to the chief scientist of the China Automotive Technology and Research Center (CATARC).
Reports indicate that the draft GB/T standard titled “Solid-state batteries for electric vehicles Part 1: Terminology and Classification” was completed in December 2025 and opened for public comment until February 28, 2026. According to Mydrivers, CATARC will conduct verification tests in February 2026 to further refine testing methods and confirm evaluation criteria.
The new standard is expected to complete review and approval by April 2026, with official implementation scheduled for July the same year. The standard will focus on fundamental information related to solid-state batteries, including defining key terminology such as liquid batteries, solid-liquid batteries (semi-solid), and all-solid-state batteries.
Additional sections of the standard are expected to be released in the future, covering guidelines and requirements related to solid-state electrolytes and other components. Many Chinese automakers and battery manufacturers are actively developing this battery technology due to its advantages, including higher energy density and improved resistance to fire.
Solid-state batteries offer an energy density exceeding 300 Wh/kg. A notable example is the latest battery developed by Dongfeng, which has begun testing a 350 Wh/kg battery installed in the eπ 007 electric sedan. The company claims the battery could enable a driving range of more than 1,000 kilometers on a single charge, while maintaining 72% energy retention at temperatures as low as -30 degrees Celsius.
Previously, Chinese scientists announced a breakthrough in developing a silicon nanowire anode with a “breathable” structure for solid-state batteries. The technology enhances safety, increases energy density, and improves long-term cycle performance. Reports also suggest that BYD, Geely, Chery, GAC, Dongfeng, FAW, and other automakers plan to begin installation trials of all-solid-state batteries starting next year.
