Thermal Analysis on Lithium Primary Batteries

To evaluate the thermal safety of lithium battery, its electrolyte was assessed by CHETAH (Chemical Thermodynamic and Energy Release) and measured by a Differential scanning calorimeter (DSC), since it is a reactive material and causes accidents. Moreover, thermal reactivities of coin type primary lithium, silver oxide and alkaline batteries were analyzed by using a modified closed pressure vessel test (MCPVT). As a result, lithium battery is more hazardous than the other types of batteries. This might be a reason why recently with its increasing usage or disposal, accidents increased when used lithium batteries are thrown into other domestic wastes.
