PURPOSE:To obtain a titled battery which shows excellent low temperature discharge characteristic after the storing by utilizing non-aqueous electrolyte obtained by dissolving lithiumtrifluoromethanesulphonate into the mixed solvent including propylenecarbonate and dioxolane. CONSTITUTION:A solvent forming non-aqueous electrolyte is prepared as a mixed solvent including propylene carbonate and dioxolane and a solute is lithiumtrifluoromethanesulphonate. For example, the solution obtained by dissolving lithiumtrifluoromethanesulphonate of 1mol/litterk to the mixed solvent of propylenecarbonate and dioxolane with mixing ratio of 1:1 is used as the electrolyte. The positive electrode can be obtained by pressurizingly molding a mixture of manganese dioxide which has been heat-processed as the active subtance, carbon powder as conductive agent and fluorine resin powder as a bindier mixed in the weight ratio of 85:10:5, while the negative electrode can be obtained by punching a lithium rolled plate in the predetermined size. |
