PURPOSE:To improve conservation and cycle properties, by controlling reaction between a positive electrode, a negative electrode and an electrolyte at the time of charging through predetermining the organic solvent and lithium salt which constitute the electrolyte. CONSTITUTION:A battery is formed out of a chargeable positive electrode, a lithium negative electrode and an electrolyte of lithium salt dissolved in a organic solvent. The organic solvent is of a S-O bond, at least one or more selections among the group of sulfolane, 3 methyl-sulfolane, dimethyl sulfite, dimethyl sulfone and dimethyl sulfoxide. The lithium salt is a fluorine Lewis acid lithium salt, at least one selection among the group of trifluoromethane sulfonate lithium, hexafluorophosphate lithium, tetrafluoroborate lithium, hexafluoroarsenate lithium and hexafluoroanimonate lithium. |
