摘要：

The influence of additives in electrolyte solutions on overcharge tolerance and cycle life of rechargeable lithium cells is examined. The electrolyte solution employed in this work was 1 M LiClO4-propylene carbonate. The additives we studied were ten organic aromatic compounds. Biphenyl is well-known as an overcharge protection additive. The purpose of this work was to find additives with higher oxidation potential and longer charge-discharge cycle life than biphenyl. Summarizing the results, cyclohexylbenzene and hydrogenated diphenyleneoxide exhibited better performance than biphenyl.
