摘　　要：随着工业化进程的不断推进,全球都面临着巨大的环境压力和能源危机,煤炭、石油、天然气等传统的化石能源不能满足长期发展的需求,人们转而寻求更加环保、可持续的新能源。动力锂电池作为新能源汽车的核心部件,具有单体电压高、比能量高、放电率低和寿命长等优点,但在使用过程中也存在着续航能力差、低温充电困难、电池泄露、热失控等风险。文章分析了动力锂电池存在的使用风险及应对措施,并且提出了从产品出厂检测和使用过程监测两方面共同保障锂电池安全运行的建议。With the continuous advancement of industrialization, the world is facing huge environmental pressure and energy crisis, coal, oil, natural gas and other traditional fossil energy cannot meet the needs of long-term development, and people turn to seek more environmentally friendly and sustainable new energy. As the core component of new energy vehicles, power lithium batteries have the advantages of high monomer voltage, high specific energy, low discharge rate and long life, but there are also risks such as poor endurance, difficulty in charging at low temperatures, battery leakage, and thermal runaway during use. This paper analyzes the risks and countermeasures of power lithium batteries, and puts forward suggestions to jointly ensure the safe operation of lithium batteries from the aspects of product factory testing and use process monitoring.
