China is taking a decisive step toward the commercialization of next-generation electric vehicle technology. With plans to formalize its first national framework for solid-state batteries, the move signals a major milestone in the global EV race. As China is set to introduce the first solid-state EV Battery standard, automakers are already accelerating real-world testing of this long-promised breakthrough.
New National Standard Set for 2026
In December, China’s National Automotive Standardization Technical Committee released the first draft of a framework titled “Solid-State Battery for Electric Vehicle – Part 1: Terms and Classification.” The draft has been opened for public consultation until February 26, 2026. After review and deliberation in April, the finalized version is expected to be officially released in July 2026.
According to Wang Fang, chief scientist at the China Automotive Technology and Research Center (CATARC), the goal is to bring clarity and structure to the rapidly evolving sector. As China plans to introduce the first solid-state EV Battery guidelines, it aims to clearly define terminology and classification standards—an essential step for large-scale commercialization.
Clear Classification of Battery Types
The proposed framework categorizes solid-state batteries into several configurations:
- Liquid
- Hybrid
- Semi-solid
- Solid-liquid
- All-solid-state
Batteries will also be classified by electrolyte type, including sulfide, oxide, composite, polymer, and halide. Additionally, distinctions will be made based on conducting ions (lithium or sodium) and application focus, such as high-energy or high-power systems.
One notable provision sets the allowable weight-loss rate for a battery to qualify as solid-state at no more than 0.5%. Whether this benchmark remains unchanged will be determined during the final review process. Such definitions are crucial for China to introduce the first solid-state EV Battery regulations to standardize the industry.
Automakers Move Into Real-World Testing
Leading Chinese automakers are already testing solid-state battery systems in real vehicles. Dongfeng, GAC, BYD, and Geely have launched pilot programs.
On February 10, FAW Group announced it had installed what it described as the industry’s first lithium-rich manganese semi-solid-state battery in a vehicle. The company claims the battery achieves over 500 Wh/kg energy density and powers a 142 kWh pack capable of delivering more than 1,000 km of range under the CLTC cycle.
Dongfeng has also begun cold-weather testing of its 350 Wh/kg battery system, which similarly promises over 1,000 km of CLTC range.
Production Timeline and Global Competition
Major Chinese automakers—including BYD, FAW, and Dongfeng—are targeting initial production around 2027, with early adoption likely in premium models. Mass production is projected to be closer to 2030.
International competitors such as Toyota, Mercedes-Benz, BMW, Nissan, and Volkswagen are on comparable timelines. Mercedes-Benz recently tested a modified EQS equipped with solid-state batteries for 1,205 km on a single charge. The cells were supplied by US-based Factorial Energy, which also collaborates with Hyundai, Kia, Stellantis, and Karma Automotive.
The Bigger Picture
Solid-state batteries promise higher energy density, improved safety, faster charging, and longer range compared to conventional lithium-ion batteries. As China introduces the first solid-state EV Battery standards, it could significantly influence the global EV ecosystem, providing a structured framework just as the technology shifts from laboratory development to real-world deployment.
With testing accelerating and standards nearing completion, the next phase of the EV revolution is quickly taking shape.
