The national standard GB/Z 214-2026 "Technical Specification for Solid Electrolytes for Solid-State Batteries of Electric Vehicles," jointly issued by the State Administration for Market Regulation of the People's Republic of China and the Standardization Administration of the People's Republic of China, and co-compiled by GRGTEST, was officially released and came into effect on July 30,2026.

Notice on the Release of Standard

Standard information

The "Technical Specification for Solid Electrolytes Used in Solid-State Batteries for Electric Vehicles" applies to solid electrolyte membranes used in solid-state batteries for electric vehicles. For the first time, this specification systematically defines five key performance indicators-namely, ion conductivity, electron conductivity, electrochemical stability window, air stability, and water content-along with the corresponding testing methods, thereby providing a unified benchmark for material development, incoming material inspection, and product acceptance.

The core technical specification parameters are as follows:

The issuance and implementation of this standard hold profound strategic significance:

Establishing a unified evaluation methodology-adopting a consistent benchmark to address the issue of "fragmentation": for the first time, a unified evaluation framework for solid electrolyte membranes has been developed, enabling mutual recognition of test results across upstream and downstream sectors and reducing collaborative costs within the industrial chain.

Define technical pathways-guide technological direction: identify the key technical thresholds for both polymer-based and sulfide-based approaches, thereby directing research, development, and capital resources toward mainstream technical pathways.

Addressing critical safety challenges – supporting security and quality control: metrics such as air stability and moisture content directly target the industrial pain points associated with the water-and oxygen-sensitive nature of solid electrolytes, enabling the management of safety risks at the source.

Overcoming industrialization bottlenecks – Accelerating industrialization: Providing foundational, common standard support to facilitate the transition of solid-state batteries from laboratory research to automotive-grade mass production, while shortening the material–cell validation cycle.

Serving national strategic objectives - supporting industry development: facilitating forward-looking technological planning for new energy vehicles and solid-state batteries, and refining the standardization framework for key materials in power batteries.
