为解决目前煤矿井下紧急避险设施用锂离子蓄电池安全应用方面缺乏针对性研究的现状,基于紧急避险设施实际应用需求,充分吸收、借鉴现有研究与应用成果的基础上,选择紧急避险设施中普遍应用的60 A·h矿用磷酸铁锂蓄电池为研究对象,针对电池正极与隔膜等材料的优选、最大允许使用容量的合理限制、安全性能检测检验方法的确定以及充放电循环后的安全性判定等,影响锂离子蓄电池安全性的诸多方面,进行大量测试方法研究与对比试验分析,提出电池材料选择、检测检验等方面的特殊安全要求,为锂离子蓄电池在紧急避险设施中安全应用提供依据。

In order to solve the lack of the targeted study status in the safety application of the lithium ion battery to the emergency refuge facility in the present un derground mine, based on the actual application requirements of the emergency refuge facility, with a full absorption and references of the available study and applicati on achievements, the 60 A.h lithium iron phosphate battery generally applied to the emergency refuge facility was selected as the study object. According to the optimiz ed selection on the battery anode and membrane as well as other material, the rational restriction of the max allowed applied volume, the determination of the safety pe rformance inspection and test method, the safety adjustment after the charge-discharge cycle and others, large number test method study and comparison test analysis were conducted on the many safety aspects of the lithium ion battery. The special safety requirements of the battery material selection, inspection and test and other as pects were provided in order to provide the references to the safety application of the lithium ion battery in the emergency refuge facility.
