Study on thermal runaway test and evaluation of lithium manganese non-rechargeable battery

This paper mainly studies the thermal runaway phenomenon of lithium manganese disposable battery, triggers the thermal runaway of the product by heating, monitors the voltage and internal resistance state parameters of the product, and analyzes the performance changes of the cell. Understand the process of thermal runaway according to the temperature change of the cell and the pressure change inside the cavity of the thermal runaway device (accelerated calorimeter, ARC). Through the ideal gas state equation, the release equivalent amount of thermal runaway gas in the cell are analyzed. Through the thermal runaway test, explore the parameter state changes of lithium manganese battery under extreme conditions, and deepen the thermal safety research of lithium manganese battery.
