Overcharge reaction of lithium-ion batteries
Overcharge reaction was studied in detail using 650 mAh prismatic hermetically sealed lithium-ion batteries with LiCoO 2 cathodes, graphitic carbon anodes and ethylene carbonate/ethyl methyl carbonate (EC/EMC) electrolytes. Several varieties of gases (CO 2, CO, H 2, CH 4, C 2H 6 and C 2H 4) were evo...

| description | Overcharge reaction was studied in detail using 650
mAh prismatic hermetically sealed lithium-ion batteries with LiCoO
2 cathodes, graphitic carbon anodes and ethylene carbonate/ethyl methyl carbonate (EC/EMC) electrolytes. Several varieties of gases (CO
2, CO, H
2, CH
4, C
2H
6 and C
2H
4) were evolved in the overcharge reaction. The amount of gas increased with the increase in the cell temperature and rose rapidly at the end of the overcharge. In particular, the amount of CO
2 gas produced by the oxidation of the electrolyte at the cathode increased markedly. The exothermic oxidation reaction of the electrolyte was accelerated at the temperature above 60
°C, causing the cell temperature to increase rapidly thereafter. The heating tests of the overcharged anode samples enclosed in cylindrical cell cases with EC/EMC electrolytes resulted in thermal runaways. In contrast, the overcharged cathodes tested in the same manner showed no thermal runaway. The thermal runaway reaction during overcharge was caused by the violent reaction between the overcharged anode (deposited lithium) and the electrolyte solvent at high temperature that was the result of the rapid exothermic reaction of the delithiated cathode and the electrolyte. |
