摘　　要：为了研究射流水柱与低温氮气对由穿刺引发的锂离子电池热失控火灾的防控效果,开展了不同灭火剂种类(射流水柱与低温氮气)及不同灭火剂作用时间下的锂离子电池火灾灭火试验。研究结果表明:射流水柱灭火剂可用作扑灭锂离子电池火灾,但无法彻底阻断内部反应的进行,需较长时间持续释放作用以免发生复燃。相同作用时间内低温氮气无法持续有效地对电池进行降温,且作用期间电池存在较大复燃风险,针对锂离子电池火灾适用性较差。To study the prevention and control effect of water and low-temperature nitrogen on lithium-ion battery fire caused by puncture,different battery models,different types of fire extinguishing agents and different action time of fire extinguishing agents were selected to carry out lithium-ion battery fire extinguishing experiments.The results show that water agent can be used to extinguish the fire of lithium-ion battery,but it cannot completely block the internal reaction.It needs to be released for a long time to avoid reignition.Low temperature nitrogen cannot effectively cool the battery within the same action time,and the battery has a great risk of reignition during the action period of low temperature,so it has poor applicability for lithium-ion battery fire.
