摘　　要：安全性是高容量及动力型锂离子电池商品化的主要障碍。当在热冲击、过充、过放、短路等滥用状态下,电池内部的活性物质及电解液等组分间将发生化学、电化学反应,产生大量的热量与气体,当积累到一定程度就会引起电池的着火、爆炸。本文综述了电池内部热量的来源和产生的原因,分析了电池在加热、过充、短路等状态下的爆炸机理,并提出了解决电池爆炸问题的具体措施。One of the obstacles to commercialize high capacity and high power lithium-ion batteries is safety properties. The explosion of battery results from the heat and pressure accumulation by internal component reactions under abuse conditions, such as overheating, overcharge, short-circuit and so on. In this paper, the main heat sources are summarized, such as cathode and anode decomposition, electrolyte decomposition, the reaction between electrolyte and electrodes. The explosion mechanism of lithium-ion battery is analyzed under high temperature heat test, overcharge and short-circuit. The measures to improve battery safety are suggested.
