一种锂离子电池爆炸原因测试方法
摘要：
本发明公开了一种锂离子电池爆炸原因测试方法，它是通过建立爆炸原因的标准，对发生爆炸的电池的残留物进行收集，然后研磨过筛得到粉体，并对过筛后的产物进行差示扫描量热分析；将分析所得的差示扫描量热分析(DSC)曲线与标准参照图进行比较以确定其爆炸原因。标准参照图是通过分析标准锂离子电池的特定爆炸原因所得到的差示扫描量热分析(DSC)曲线。本发明操作方法简单，分析结果准确，能较好的分辨出锂电池引起的爆炸的原因。
摘要（英）：

The method of ascertaining cause of lithium ion cell explosion includes: setting explosion cause standard, collecting the residues of the exploded cell, grinding and sieving to obtain powder, differential scanning and calorimetric analysis on the powder, and comparing the obtained differential scanning and calorimetric curve with the standard map to determine the explosion cause. The standard mapis differential scanning and calorimetric curve obtained through analyzing the specific explosion cause of standard lithium ion cell. The present invention has simple operation and accurate analysis results.
