摘要
随着新能源产业的快速发展,锂离子电池作为重要的储能介质得到广泛应用,然而其造成的火灾安全问题也愈发严重。电池灾害本质上由内部放热副反应所致,产生的高温及可燃气体会进一步造成火灾、爆炸事故。然而,热失控演变特征受诸多因素影响,主要包括电池内部状态、结构和外部环境,在不同条件下演变特征的差异性较为显著。本文梳理了近几年不同内、外部因素影响下电池热失控演变特性的相关研究,总结了电池热失控特性关键演变特征,并给出研究建议及展望。
With the rapid development of the renewable and sus-tainable energy industry,lithium-ion batteries have been widely used as the electric energy storage media,but the fire safety is-sues have also become more serious.Battery disasters are essen-tially caused by internal heat release of side reactions,resulting in large amount of heat and combustible gases,which can further cause fire and explosion hazards.However,the evolution charac-teristics of thermal runaway are affected by many factors,which are mainly the internal state,structure of the battery and the exter-nal environment,and the differences of the evolution characteris-tics are significant under different conditions.This paper reviews the relevant research on the characteristics of battery thermal run-away under different internal/external factors,and key character-istics have been highlighted.Furthermore,research suggestions and prospects are proposed.
