为充分认识软包型高能量密度三元锂离子电池发生热失控的条件和后果，采用电池绝热量热仪分别考察了不同类型镍钴锰三元软包锂离子电池的热失控反应特性，得到了不同能量密度电池的热失控起始放热温度、热失控触发温度、绝热温升、达到最大反应速率时间等热安全参数的变化规律，讨论了软包型高能量密度锂离子电池发生热失控的条件和机理，提出了表征电池热失控危险特性的安全判据。高能量密度软包型锂离子电池最低在50℃左右即可发生自反应放热，120～180℃时发生不可逆热失控，该过程产生大量气体导致鼓包、破裂，电池材料燃烧后最高温度可达600℃。研究得到的电池关键量热参数和规律能够为动力电池及储能系统的风险评估、监测预警和安全防护等提供基础数据和理论依据。
