The safety standards of lithium-ion batteries are the core guidelines for regulating their entire life cycle of production, testing, use and disposal, and an important support for ensuring personal safety, environmental safety and the orderly development of the industry. With the wide application of lithium-ion batteries in consumer electronics, new energy vehicles, energy storage, industrial equipment and other fields, accidents caused by their potential safety hazards have attracted much attention. Unified and strict safety standards can effectively avoid risks such as battery bulging, leakage, fire and explosion, standardize enterprise production behavior, guide the high-quality development of the industry, and provide clear guidelines for users' safe use.

　　The safety standards of lithium-ion batteries cover the entire life cycle, which are mainly divided into three categories: production and manufacturing standards, performance safety standards, and use safety standards. Different countries and regions have formulated targeted standard specifications based on their own industrial characteristics. The mainstream international safety standards include IEC (International Electrotechnical Commission) standards and UN (United Nations) transportation standards. Domestically, GB (National Standards) is the core, covering industry standards and enterprise standards, forming a multi-level and comprehensive safety standard system to ensure that every link of the battery from production to disposal has rules to follow.

　　Production and manufacturing standards focus on source control, requiring enterprises to strictly control the purity of electrode materials, electrolyte ratio, and cell assembly accuracy, prohibit the use of unqualified raw materials, and standardize the temperature and humidity of the production environment to avoid potential safety hazards caused by process defects during production. Performance safety standards are the core content, which clearly stipulate the safety requirements of the battery under extreme conditions such as overcharge, over-discharge, short circuit, extrusion, puncture, high temperature and low temperature. For example, the battery must have automatic power-off protection when overcharged, and no fire or explosion shall occur when squeezed or punctured; in addition, it also clearly stipulates the capacity attenuation rate, cycle life, temperature resistance and other aspects of the battery. Use safety standards, targeting different application scenarios, clearly specify the battery's use specifications, charging requirements, storage conditions and disposal requirements, prohibit random disassembly and disposal of waste batteries, standardize the use of chargers, and avoid safety accidents caused by improper use. Today, with the iteration of battery technology, safety standards are also continuously upgraded, further improving the safety performance of lithium-ion batteries, promoting the green, safe and sustainable development of the new energy industry, and building a solid safety line for battery applications in various scenarios.
