There are two forms of short circuit, namely internal short circuit (ISC) and external short circuit (ESC). ISC means that the positive and negative electrodes are connected inside a battery while ESC means that the positive and negative electrodes are connected outside a battery. Due to the complex electro-thermal coupling characteristics
