摘要： 以某锂电池化成车间发生的爆燃事故为对象，利用现场勘验、调查询问、视频分析等火灾调查方法，剖析事故直接原因和灾害成因。开展5类10余次三元锂电池跌落试验，总结不同状态锂电池发生外短路、产生热失控现象的关联性，旨在深入分析锂电池生产端的火灾事故，探讨与之对应的防范和处理建议，以降低锂电池工厂火灾事故发生概率，保证工厂安全稳定运行。

Abstract: This paper focuses on a combustion and explosion incident that occurred in a lithium battery formation workshop. By employing fire investigation methods such as on-site inspection, investigative inquiries, and video analysis, the direct causes of the accident and the factors contributing to the disaster are dissected. Over ten drop tests were conducted on ternary lithium batteries across five categories to summarize the correlation between external short circuits and the occurrence of thermal runaway in lithium batteries under different conditions. The study aims to provide an in-depth analysis of fire incidents at the production end of lithium batteries, discuss corresponding prevention and handling recommendations, reduce the probability of fire accidents in lithium battery factories, and ensure the safe and stable operation of the facilities.

Key words: ternary lithium batteries, formation process, external short circuit, fire investigation, lithium battery production
