Abstract

The heat character of Lithium-ion battery materials and explosion mechanism of Lithium-ion cells under the overcharge,short-circuit and other abuse behavior are tested by C₈₀ calorimeter, DSC and charge-discharge instrument.SEI reactions, Li_xC₆/electrolyte and Li_xC₆/PVDF reactions take place at the anodes. Electrolyte and solvent reactions happen after 178℃ and Li_1-xCo_1/3Ni_1/3Mn_1/3O₂ decomposes after 230℃. The batteries explode at 150℃ oven test or 1.5C, 5.5 V overcharge and do not explode at short-circuit.
