Abstract:The energy released by failure of rechargeable 18-mm diameter by 65-mm long cylindrical (18650) lithium-ion cells/batteries was measured in a bomb calorimeter for four different commercial cathode chemistries over the full range of charge using a method developed for this purpose. Thermal runaway was induced by electrical resistance (Joule) heating of the cell in the nitrogen-filled pressure vessel (bomb) to preclude combustion. The total energy released by cell failure, ∆Hf, was assumed to be comprised of the stored electrical energy E (cell potential x charge) and the energies of mixing, chemical reaction, and thermal decomposition of the cell components, ∆Urxn. The contribution of E and ∆Urxn to ∆Hf was determined, and the mass of volatile, combustible thermal decomposition products was measured in an effort to characterize the fire safety hazard of rechargeable lithium-ion cells.
