PURPOSE:To suppress increase in internal resistance and improve storage performance by adding indium chloride to nonaqueous electrolyte of nonaqueous electrolyte battery using lithium or lithium alloy as a negative electrode. CONSTITUTION:A cupric oxide positive electrode 1 is pressed against the inner bottom of a positive can 3 through a positive current collector 2. A lithium negative electrode 4 is pressed against the inner bottom of a negative can 6 through a negative current collector 5. In addition, a separator 7, an insulating gasket 8, and a positive inner can 9 are used to assemble a nonaqueous electrolyte battery. A nonaqueous electrolyte is prepared by dissolving 1.0mol/l of lithium perchlorate into the mixed solvent of propylene carbonate and 1,2- dimethoxyethane, and adding 0.01mol/l of indium chloride thereto. Indium ions in the electrolyte react with impurities or active sites in the positive electrode to suppress increase in open circuit voltage after storage. |
