Abstract

With the rapid development of new energy vehicles, people pay more and more attention to the safety problems caused by lithium-ion batteries. If they are not solved, this will inevitably affect the popularization of new energy vehicles in my country. This article introduces the current research progress of thermal runaway of lithium batteries. Firstly, it analyzes the causes of thermal runaway of lithium batteries from the perspective of kinetics, and then focuses on the analysis of the mechanism of battery thermal runaway caused by internal short circuit, external short circuit, overcharge, and overdischarge. In view of the main research progress in these aspects, finally put forward suggestions for the research of lithium batteries.
