摘要:
为研究锂电池在民航飞行低压特殊环境的安全性及发生热失控灾害后的高温危险性，通过可模拟飞行变动条件的动压变温实验舱开展系列实验，研究锂电池在不同低压环境下的（101，60，30 kPa）多节18650型锂离子电池热失控温度特性，采集电池池体温度及热失控喷射释放温度等参数。研究结果表明：随环境压力降低，圆柱锂电池间的热失控传播并不能被阻断，但锂电池热失控灾害所释放产生的高温区域减少，且高温持续时间变短，释放所产生温度的高温危险性随环境压力的降低而有所降低。
Abstract:
In order to study the safety of lithium batteries in the special low pressure environment of civil aviation flight,as well as its high temperature risk when occurring the thermal runaway hazard,the serial experiments were carried out in the dynamic pressure and temperaturevarying experimental cabin,which can simulate the flight changing conditions.The temperature characteristics of thermal runaway for the multipack type 18650 lithium ion batteries under different low pressure environments (101 kPa,60 kPa and 30 kPa) were experimentally studied,and the parameters such as the body temperature and thermal runaway jet release temperature of the batteries were measured.The results showed that the decrease of environmental pressure could not block the thermal runaway propagation between the cylindrical lithium batteries,but the high temperature zones generated by the thermal runaway hazard release of lithium batteries decreased,and the duration of high temperature decreased,so the high temperature risk caused by the temperature produced by the release decreased with the decrease of environmental pressure.
