Thermal Runaway Initiation Methods for Lithium Batteries
The overheat method was the quickest and most repeatable method for producing a thermal runaway event. Lithium cobalt oxide (LiCoO₂) cylindrical secondary cells at 30% SOC, of type 18650 3.7V 2600mAh were tested at various heating rates. The results suggest that the heating rate significantly affects an 18650-sized cell's thermal runaway.
