摘　　要：理解低压环境下锂离子电池热失控特性,对高原低压环境电池储能系统的安全运行以及航空运输至关重要。对低压环境下锂离子电池单体的热失控特性[包含喷发特性、表面温度、点燃时间、热释放速率(HRR)、质量损失率(MLR)和总产热量(THR)等]以及电池模组热失控蔓延特性进行综述。低压环境下,锂离子电池单体燃爆响应时间变长,HRR、MLR和THR均降低。对今后的研究方向给出建议,为低压环境下锂离子电池的安全设计提供理论支持。Understanding the thermal runaway characteristics of Li-ion battery in low-pressure environments was crucial for the safe operation of battery energy storage systems and transportation by air to high-altitude locations.The thermal runaway characteristics of Li-ion battery in low-pressure environments[including spray characteristics,surface temperature,ignition time,heat release rate(HRR),mass loss rate(MLR)and total heat release(THR),etc.]and the thermal runaway propagation characteristics of battery module were summarized.The explosion response time of Li-ion battery became longer,the HRR,MLR and THR decreased under low-pressure environment.Suggestions to the future research direction was given.Theoretical support for the design on Li-ion battery safety in low-pressure environments was provided.
