Li-Ion Battery Short-Circuit Protection by Voltage-Driven …
Overcharging and overdischarging are the most frequent causes of a thermal runaway [2–6]. They lead to an internal short circuit by dendrites formed from lithium during overcharging [7,8] and from copper during overdischarge [9,10]. An internal short circuit, as well as an external short circuit, lead to an instantaneous increase
