摘要

研究L iCoO2(或L1.05Co1/3N i1/3Mn3O2)/L ixC6锂离子电池材料的热分解特性以及锂离子电池在加热、过充、短路等情况下的爆炸机理.实验表明,50~350℃之间负极表面存在SEI膜的分解、L ixC6与电解液乃至L ixC6与PVDF等3种放热反应,电解液于178℃时开始放热,L i1-xCo1/3N i1/3Mn1/3O2的热分解反应起始于230℃.锂离子电池在150℃加热时爆炸,1.5 C过充至15 m in时爆炸,短路情况下不发生爆炸.

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 C_(80) calorimeter,_()DSC and charge-discharge instrument.SEI reactions,Li_xC_(6)/electrolyte and Li_xC_(6)/PVDF reactions take place at the anodes.Electrolyte and solvent reactions happen after 178℃ and Li_(1-x)Co_(1/3)Ni_(1/3)Mn_(1/3)O_(2) decomposes after 230℃.The batteries explode at 150℃ oven test or 1.5C,5.5 V overcharge and do not explode at short-circuit.
