摘要： 搭建了一套灭火实验平台，以额定容量为75 Ah的三元软包锂离子电池单体为研究对象，采用恒定功率为1 000 W的铝铸加热板诱发电池热失控，分析了电池在50%SOC下的燃烧特性，研究了溴代三氟丙烯（2-BTP）对电池火灾的灭火降温效果，并在相同工况下与水、七氟丙烷、五氟乙烷进行对比，分析了不同灭火剂的灭火时间、最高温度和复燃情况。结果表明，实验条件下，溴代三氟丙烯最快在13 s内扑灭了明火，不仅灭火速度最快，降温效果最好，还能有效抑制锂离子电池复燃。

Abstract: Abstract: A set of fire extinguishing experimental platform was set up, the rated capacity of 75 Ah ternary flexible lithium-ion battery was taken as the research object . A constant power of 1 000 W aluminum casting heating plate was used to induce thermal loss of the battery. The combustion characteristics of the battery under 50% SOC were analyzed, and the effect of 2-BTP on battery fire suppression and cooling was studied.?Compared with water, FM-200 and HFC-125 under equal working conditions, the fire extinguishing time, maximum temperature and re-ignition of different extinguishing agents were analyzed.?The experimental results show that under the set conditions, 2-BTP is the fastest to extinguish the flame within 13 s. 2-BTP not only has the fastest fire-extinguishing speed and the best cooling effect, but also can effectively inhibit the re-ignition of lithium ion battery.
