PURPOSE:To obtain a nonaqueous electrolyte battery whose storage performance in a high temperature and high humidity condition is good by using a mixed solvent of propylene carbonate and tetrahydrofuran as a solvent of electrolyte and lithium trifluoromethanesulfonate or lithium decachlorodecaborate as a solute. CONSTITUTION:A mixed solvent of propylene carbonate and tetrahydrofuran, for example, having a mixing ratio of 1:1, is used as a solvent. For example, 1mol/l of lithium trifluoromethanesulfonate is dissolved in the mixed solvent to use as electrolyte. For example, a positive electrode is prepared by mixing carbon powder as conductor and fluorine resin powder as binder to heat-treated manganese dioxide active material, and molding the mixture, then heating the molded mix. A negative electrode is prepared by punching rolled lithium plate in a specified dimension. |
