Mechanism of External Short Circuit in Li-Ion Battery In general, the test item of an external short circuit in a Li-ion battery is to determine the criteria of the level of risk by connecting exposed cathode and anode electrodes to a short resistor.
The high temperature caused by the external short circuit results in the physical deformation of the separator of the battery cell located between the anode and the cathode platforms, and then it leads to an internal short circuit and a serious thermal reaction.
Sensors record the cell's reactions. Testing the battery response to the induced internal short provides a 100% reliable testing method to safely test battery containment designs for thermal runaway.
