PURPOSE:To provide an organic electrolytic battery with excellent storage characteristics in the high temperature storage exceeding 80 deg.C by using an organic electrolyte containing carbon dioxide gas. CONSTITUTION:In a lithium battery consisting of a negative electrode 3 that uses metal lithium as an active material, a positive electrode 5 that uses a solid type active material composed of various metal oxides, halide, and sulfide, and an organic electrolyte that dissolves inorganic salt in an organic solvent, an organic electrolyte that dissolves 1mol lithium boride and fluoride in a mixed solvent of propylene carbonate and 1,2-dimethoxyethane and contains carbon dioxide gas in saturation status is used as the electrolyte. As shown in the figure, in a cell (A) of this invention that uses the electrolyte containing carbon dioxide gas, the deterioration of the cell capacity is approximately 7% at a storage of 80 deg.C even in three months and a non-processed cell (B) has approximately 15% deterioration. In a cell (C) without dissolved carbon dioxide gas, the capacity deterioration exceeds 50%.
