Abstract. Lithium ion batteries (LIBs) are booming due to their high energy density, low maintenance, low self-discharge, quick charging and longevity advantages. However, the thermal stability of LIBs is relatively poor and their failure may cause fire and, under certain circumstances, explosion. The fire risk hinders the large scale
