China’s First National Standard for Solid-State Batteries Opens for Public Comment; No Longer References to “Semi-Solid” Technologies
2026/01/06
Recently, the first national standard for solid-state batteries—“Solid-State Batteries for Electric Vehicles, Part 1: Terms and Classification”—was released for public comment. This move marks the transition of solid-state battery technology from the laboratory to industrial application, laying a solid foundation for the industry’s development.
The draft for public comment provides detailed definitions of key terms, classifications, and coding systems related to solid-state batteries, categorizing them into various types such as sulfide-based, oxide-based, and polymer-based systems, with further subdivisions based on the type of ion-conducting material and application areas. In terms of evaluation criteria, the new national standard stipulates that the weight-loss rate of solid-state batteries shall not exceed 0.5%, which is more stringent than the previous industry standard, thereby ensuring the purity and performance of solid-state batteries.
Currently, there is no unified national or international standard for automotive solid-state batteries. The development of this national standard will help put an end to the industry’s confusion over competing concepts, harmonize technical specifications, foster collaborative development across the value chain, and enhance China’s competitiveness in the global solid-state battery sector.
With the introduction of the new national standard, the commercialization of solid-state batteries is expected to accelerate. Globally, governments and companies in numerous countries are racing to expedite the R&D and technology transfer of solid-state battery technologies. As a major producer of lithium-ion batteries, China’s strong policy support and the proactive efforts of industry players will drive the steady implementation of solid-state battery R&D and gradually enable large-scale mass production.
Recently, China’s solid-state battery industry has entered a phase of intensive capital infusion, with several leading companies securing major funding rounds that provide critical financial support for the sector’s leapfrog development. At the same time, listed companies on the A-share market that have positioned themselves along the solid-state battery value chain are attracting significant attention from institutional investors, with many firms receiving frequent research visits—underscoring the market’s strong confidence in the technology’s future prospects.
