摘　　要：以锂电池作为动力来源的高科技产品目前已成为生活的必需品,由于锂电池本身的化学特性,由锂电池引发的公共安全事件与日俱增,特别是锂电池自燃、爆炸及电解液泄漏3类主要事故,严重威胁公众的安全。该文从公众安全视角出发,分析诱发锂电池安全事故的因素,并用鱼骨图形式清晰表达出来,总结这些因素可能导致的事故类型,用LEC评级法评估诱发事故的风险等级大小,找出诱发锂电池事故的主要原因,并提出锂电池安全事故主要防范方向。At present,high-tech products powered by lithium batteries have become the necessities of life.Due to the chemical characteristics of lithium batteries,public safety incidents caused by lithium batteries are increasing day by day,especially the three major accidents of lithium battery spontaneous combustion,explosion and electrolyte leakage,which seriously threaten the safety of the public.From the perspective of public safety,this paper analyzes the factors that induce lithium battery safety accidents,and clearly expresses them in the form of fishbone diagram,summarizes the types of accidents that may be caused by these factors,evaluates the risk level of induced accidents by LEC evaluation method,finds out the main causes of lithium battery accidents,and puts forward the main prevention direction of lithium battery safety accidents.
