使用FTT锥形量热仪对锂离子动力电池电芯材料进行燃烧性能测试。使用DTG-60AH型差热-热重同步分析仪研究电芯材料的热分解性。基于所获实验数据的分析能够确定不含电解液的锂离子动力电池电芯材料不发生燃烧,在25、35、50kW/m~2辐射通量下释放的CO、CO_2气体量不会对人体造成明显伤害,其火灾危险性很小。电芯材料的失重和热解分为22.0~162.1℃和325.0~600.0℃两个阶段。研究结果可以为锂离子动力电池在电动飞机和电动汽车中的安全使用提供帮助。
The FTT calorimeter was used to test the combustion performance of lithium-ion battery cells. DTG-60AH-type differential thermal-thermal gravimetric analyzer to study the thermal decomposition of battery materials. Based on the analysis of the obtained experimental data, it can be determined that the lithium ion battery cell material without electrolyte does not burn, and the amounts of CO and CO 2 released at 25, 35 and 50 kW / m 2 flux do not affect the human body Cause significant damage, the risk of fire is small. Weight loss and pyrolysis of the cell material is divided into two stages of 22.0 ~ 162.1 ℃ and 325.0 ~ 600.0 ℃. The results of this study can help to ensure the safe use of Li-ion batteries in electric aircraft and electric vehicles.
