New standard for lithium battery testing: GB 31241-2022 Safety technical specification for lithium-ion batteries and portable electronic products.
The new standard GB 31241-2022, “Safety specification for portable electronic lithium-ion battery and battery packs”, Battery recycling line issued on December 29,2022, was officially 2024 on January 1. The formulation, promulgation and implementation of relevant safety standards are conducive to the healthy and sustainable development of the lithium-ion battery industry.
External factors such as high temperature, lithium battery welding machine overcharge, overdischarge, short circuit, etc. , will cause safety problems, such as battery leakage, fire and even explosion. Therefore, GB 31241-2022 "Technical Specification for Safety of Lithium-ion Batteries and Accumulators for Portable Electronic Products" stipulates that the purpose of this brief introduction is to introduce the principles on which the requirements of this document are based, and to understand that these principles are necessary for the design and production of safe lithium-ion batteries and accumulators. It should be noted that this document only considers the most basic safety requirements of lithium-ion batteries and battery packs, so as to provide safety protection for people and property, and does not involve performance and functional characteristics.
Further research and development of information technology and processes will inevitably require further revision of this document. mounting machine Hazards arising from lithium-ion power batteries and battery packs within the scope of this document are:
Leakage can directly lead to chemical corrosion of human body, or indirectly lead to internal insulation failure of battery-powered electronic equipment.
Danger of electric shock, fire, etc:
Fire, which directly burns human body, or causes fire hazard to electronic products powered by batteries; -Explosion, direct injury to human body or damage to equipment;
overheating, resulting in direct burns to the human body or in reduced insulation levels and the performance of safety components, or combustion of flammable liquids. The risk of leakage may be due to internal or external stresses due to damage to the shell. Thermal runaway inside the battery can cause fire and explosion hazards. A short circuit in the battery and a strong oxidation reaction of the battery material may lead to thermal runaway.
