摘要
锂离子电池的优良性能使之得到了广泛的应用,也是电化学储能电站的核心部件之一。然而储能电站的火灾、爆炸等事故,不但会给企业带来极大的经济损失,还会对整个产业的发展产生很大的影响,因此储能电站安全不容忽视。阐述了锂离子电池热失控致火灾的机理,重点归纳总结了当前国内外关于电池表面缺陷检测、电压、电流-超声波预警系统、声音预警系统和气体-声信号预警系统融合等锂离子电池热失控-火灾早期预警技术,研究了现有锂离子电池火灾灭火常用技术手段及优缺点。在此基础上,提出了适用于锂离子电池储能电站火灾的早期预警和火灾控制技术,为有效地提升储能系统安全防护水平,降低火灾发生的概率及火灾发生后的财产损失等应用提供了参考。
The excellent performance of lithium-ion batteries makes them widely used,and it is also one of the core components of electrochemical energy storage power stations.However,accidents such as fires and explosions of energy storage power stations not only bring great economic losses to enterprises,but also have great impact on the development of the entire industry.Therefore,the safety of energy storage power stations cannot be ignored.The mechanism of lithium-ion battery thermal runaway and fire,and focuses on summarizing the runaway and fire early warning technology,such as current domestic and foreign research on battery surface defect detection,voltage,current-ultrasonic early warning system,sound early warning system and gas-acoustic signal early warning system fusion are expounded.The common technical means and advantages and disadvantages of existing lithium-ion battery fire extinguishing are also studied.On this basis,a fire early warning and fire control technology suitable for lithium-ion battery energy storage power stations is proposed,which can effectively improve the safety protection level of energy storage systems,reduce the probability of fire occurrence and property damage after fire occurrence.
