Review of the thermal runaway characteristics of airborne lithium-ion batteries

The thermal safety problem of lithium-ion batteries under aviation airborne conditions is a key factor that restricts their application in the aviation field. The related scientific issues are the research hotspots at home and abroad. This paper reviews the thermal runaway problem of lithium-ion batteries and their products in aviation application and transportation. Thermal runaway characteristics and mechanisms of the batteries under low temperature, low pressure and enclosed space conditions are presented. Thermal runaway behaviors and laws of the batteries are introduced from the five aspects:thermal runaway temperature, thermal runaway time, heat release rate, mass loss, and thermal runaway spreading law. It is proposed that future research should be focused on thermal runaway behaviors of lithium-ion batteries concerning the synergistic effect of low temperature and low pressure environments.
