Comparison and Analysis of Domestic and International Standards for Lithium-ion Batteries

Small-scale lithium-ion batteries are widely used as the primary power source for portable electronic devices, such as smartphones, laptops, and wearable electronics, and their application scope continues to expand. However, owing to their structural characteristics, fire incidents involving these batteries often exhibit thermal runaway accompanied by sudden flame jetting, fragmentation, and re-ignition, posing significant safety risks to users as well as to transportation and storage environmen
