The extremely large battery resistance limited the short circuit current I ISC and the consequent joule heat Q ISC = I ISC 2 · R to a small value during ISC, and thus no visible increase was observed in the temperature rate profile. Therefore, we can conclude that ISC is not the initiation of TR during the ARC test, and the underlying TR mechanism requires further
