摘　　要：锂离子电池具有比能量高、循环寿命长、污染小等优点,成为目前最有发展前景的化学电源,应用领域也从电子产品向电动汽车、电力储能等领域逐步扩大。由其材料体系性质导致的安全性问题一直没有得到有效解决,因“热失控”引起的电池起火、爆炸事故频发,本文结合国内外相关标准对影响锂离子电池安全性的温度、电压、电流等进行了简要分析。Lithium-ion batteries have the advantages of high specific energy,long cycle life and low pollution.They have become the most promising chemical power source at present,and their application fields have gradually expanded from electronic products to electric vehicles,power storage and other fields.However,since the safety problems caused by the nature of its material system have not been effectively solved,battery fires and explosion accidents caused by"thermal runaway"occurred frequently.This paper briefly analyzes the temperature,voltage,current and other issues that affect the safety of lithium-ion batteries based on the existing international and domestic relevant standards.
