AI Technical Summary
During the operation of lithium batteries, due to short circuit or abnormal high current discharge, thermal runaway temperature is easily caused, resulting in damage to the lithium battery.
A battery cell assembly is designed, including a battery cell body and a temperature adjustment structure. The temperature adjustment structure uses a thermally sensitive material coating to adjust the resistance value of the battery cell assembly according to the temperature changes of the battery cell body to ensure that the temperature of the battery cell body is controlled within the preset range.
By effectively controlling the temperature of the battery cell, the safety performance of the battery cell is improved, the thermal runaway phenomenon is avoided, and the service life of the battery is extended.
