This study takes 40 A·h square-shaped ternary lithium-ion battery as the research object to study their gas generation characteristics after thermal runaway, and uses Accelerating Rate Calorimeter (ARC) and thermal runway gas generation performance test equipment dedicated for large capacity lithium-ion batteries to determine parameters like intensity of pressure and temperatures inside the heat & gas generation unit after thermal runway. Gas production process is introduced based on the widely used thermal runaway heat generation model, providing data support for the establishment of battery thermal runway simulation model with composite gas generation characteristics.
