The solid-state battery sector has achieved a landmark milestone. China’s proposed international standard, titled "Guidelines for the Application of Secondary Lithium-ion Batteries for Electric Vehicle Propulsion: Solid-State Batteries – Test Items and Conditions," has been officially adopted by the International Electrotechnical Commission (IEC). This marks the world’s first global benchmark in solid-state battery technology. Zhang Xiang, Secretary-General of the International Intelligent Transportation Technology Association, emphasized that the standard will establish a unified framework for global R&D in solid-state batteries and energy transition initiatives. "It will accelerate the international expansion of China’s solid-state battery technologies and products while providing critical standardization support for industrial chain enterprises to compete globally," Zhang noted.
