PURPOSE:To prevent oxidation of electrolyte and improve the storage performance without deteriorating the discharge performance, in the organic electrolyte cell containing lithium as cathode activating substance. CONSTITUTION:Salicylic acid ester is added into electrolyte. Phyenyl salicylate, p-octylphenyl salicylate etc. are used as salicylic acid ester. It is preferably to add salicylic acid ester in 0.02-0.05% by weight into electrolyte, because when the addition amount of salicylic acid ester is less than 0.02%, the oxidation preventing effect of electrolyte is not sufficient, and when the addition amount exceeds 0.5%, an increased oxidation preventing effect is obtained, but deterioration of the electric discharge performance, for example lowering of the closed circuit voltage is generated. |
