Analysis of Lithium-ion Battery Fire Accidents Based on Fault Tree Analysis Modeling

Along with the wide application of lithium-ion batteries, there are more and more researches on the fire accidents of lithium-ion batteries. At this stage, most of the studies on lithium-ion batteries focus on their performance and materials, which are also important factors affecting the fire accidents of lithium-ion batteries. Based on this, this paper explores the triggering factors of lithium-ion battery fire accidents based on the fire accident tree model, and discusses the basic events and their importance in depth, in order to provide certain reference for the prevention of lithium-ion battery fire accidents.
