Tsingyane | Kedali | Daikin Japan | Tsinghua Shenzhen Research Institute: Joint Participation in Compilation; Group Standards for Lithium Battery Structural Components Officially Implemented

Recently, the group standards Resin Materials for Lithium-ion Battery Cover Structural Components (T/SZBIA 0003—2025) and Technical Specifications for the Use of Resin Materials in Lithium-ion Battery Cover Structural Components (T/SZBIA 0004—2025), under the jurisdiction of the Shenzhen Battery Industry Association (hereinafter referred to as "the Association"), were publicly released by the Association and officially implemented on April 29, 2025. The release and implementation of these standards will set technical benchmarks for the global lithium battery industry, drive industrial technological progress, and hold far-reaching significance for the industry.

Against the backdrop of the rapid growth of the global electric vehicle and energy storage markets, large cylindrical batteries (such as 21700 and 4680) are gradually becoming mainstream, driving technological innovation in battery structural components. As battery energy density and charge-discharge rates increase, the market has put forward higher requirements for battery structural materials in terms of mechanical strength, chemical resistance, heat resistance, and electrical insulation performance. Meanwhile, the stability of the supply chain and cost control of battery structural materials have also become key factors in the industry's development.

In this context, the Association, together with global battery structural component giant Kedali, world-renowned chemical company Daikin Japan, China's top academic institution Tsinghua Shenzhen International Graduate School, and innovative enterprise Qingyan Electronics, has gathered advanced scientific research and industrial forces in the field of lithium battery structural components both domestically and internationally to take the lead in drafting the above-mentioned standards. These standards fill the current gaps in material and technical standards for lithium battery structural components, providing a reference specification for the entire industry.

Moreover, with the joint participation of international leading battery structural component enterprises, well-known foreign companies, and top research institutions, the two newly released group standards boast high authority and internationality. They provide strong technical support for the lithium battery industry and promote its further development.
