This study examines the impact of different trigger methods (thermal, mechanical, and electrical) on the thermal runaway behavior of INR21700-50E lithium-ion cells. Experiments demonstrate that the trigger method significantly impacts the reaction pathway and the overall intensity of thermal runaway. Thermal triggering is characterized by an initial phase of electrolyte evaporation, followed by hot particle […]
