Interpretation of the guidelines for the construction of the national Lithium-ion batteries industry standard system

Power battery cell is an important energy storage device that enables the mutual conversion of electrical energy and chemical energy. It is the core foundation that supports the development of industries such as intelligent terminals, electric transportation, and new energy storage. It has significant strategic significance for China's energy structure transformation, green and low-carbon development, and the achievement of carbon peak and carbon neutrality goals. The lithium battery industry chain covers mineral raw materials, key materials, battery cell manufacturing, system integration, and production equipment. The entire lifecycle includes multiple stages such as design, manufacturing, transportation, application, and recycling.

According to application scenarios, Lithium batteries are mainly divided into four categories: consumer, small power, large power, and energy storage. With the rapid development of the industry and continuous technological iteration, building a sound standard system has become an urgent need to lead the high-quality development of the industry.

The Lithium-ion batteries industry standard system first focuses on the basic and general fields, with a focus on developing unified specifications around terminology naming, transportation safety, installation, use, and maintenance, clarifying the industry's basic definitions, transportation rules, and safety operation and maintenance requirements. At the material and component level, the standard system specifies performance indicators, composition control, and testing methods for the four core materials of positive electrode, negative electrode, electrolyte, and separator, as well as key components such as current collector, housing, electrode ears, and thermal management components, to ensure the quality stability and safety of Rechargeable lithium-ion battery cell products raw materials and components from the source.

The production and testing standards of Lithium superpack batteries cover manufacturing processes, key equipment, safety production, intelligent production, and testing methods, standardize key processes such as polarizer manufacturing and chemical aging, and strengthen production safety, fire prevention and control, and intelligent management requirements. Safety and performance standards are formulated according to application scenarios, clarifying the safety requirements for various Lithium battery packs under overcharge, short circuit, compression, needle punching, and other working conditions, while regulating core performance indicators such as capacity, cycle life, and energy density. Green low-carbon standards focus on energy consumption quotas, carbon footprint accounting, green factories, and pollution control, promoting sustainable industrial development.

Recycling is an important part of the lifecycle management of Battery pack kits. The standard system focuses on two directions: hierarchical utilization and recycling, standardizing the process of residual energy detection, disassembly, classification, and material recycling of retired batteries, while strengthening pollution control and recycling management requirements.

To ensure the implementation of the standard system, the industry will take measures such as improving the construction of standardization organizations, strengthening professional talent training, expanding standard promotion and training, coordinating the efforts of industry, academia, and research, guiding enterprises to implement standards throughout the entire process, and fully leveraging the supporting role of standards in the upgrading of the Lithium solar batteries industry standards.
