摘要:
针对航空锂离子电池热失控释放气体安全性研究不足的问题，采用气体拉曼光谱技术、气相色谱仪(Gas Chromatography，GC)和质谱(Mass Spectroscopy,MS)耦合来探究压力和荷电状态(State of Charge,SOC)对锂离子电池早期故障气体类型、气体动态演变及气体潜在危险性等特征的影响规律，同时综合考虑压力、电压和电池温度等多种因素分析锂离子电池热失控危害。研究结果表明：电池SOC越高且环境压力越低，电池越早触发热失控，爆炸极限越宽，其中30 kPa下100%SOC电池热解气体爆炸极限为8.01%~53.35%；SOC和环境压力越高，电池热失控越危险，释放的气体体积越多；CO，CO2，PF3，C2H4及电解液（C3H6O2、C3H6O3、C4H8O2）等气体可作为航空锂离子电池早期故障诊断特征。研究结果对保障锂离子电池在航空领域的安全运输及应用具有重要意义。
Abstract:
In view of the lack of research on the safety of gas released from thermal runaway of aviation lithium-ion batteries,the gas Raman spectroscopy,gas chromatography and mass spectroscopy coupling (GC-MS) were used to explore the influence of pressure and state of charge (SOC) on the early fault gas type,gas dynamic evolution and gas potential risk of lithium-ion batteries.At the same time,various factors such as pressure,voltage and battery temperature were comprehensively considered to analyze the thermal runaway hazards of lithium-ion batteries.The results showed that the higher the battery SOC and the lower the ambient pressure,the earlier the battery triggered thermal runaway,and the wider the explosion limit.The explosion limit of 100% SOC battery pyrolysis gas at 30 kPa was 8.01%~53.35%.The higher the SOC and ambient pressure,the more dangerous the battery thermal runaway,and the more gas volume released.The gases such as CO,CO2,PF3,C2H4 and electrolyte (C3H6O2,C3H6O3,C4H8O2) could be used as early fault diagnosis features of aviation lithium-ion batteries.The results are of great significance to ensure the safe transportation and application of lithium-ion batteries in the aviation field.
