PROBLEM TO BE SOLVED: To surely detect the last period of discharge while preventing the cycle deterioration and suppressing the active generation of lithium in repeated charge and discharge, and provide a battery effective in commodity design by specifying the organic electrolyte per positive electrode active material. SOLUTION: The required quantity of the organic electrolyte of an organic electrolyte secondary battery is regulated to 0.27-0.37 g per 1 g of a positive electrode material. When the organic electrolyte is minimized in the generating process of lithium, lithium ion is hardly moved, the lithium ion penetrated deeply to the positive electrode is hardly desorbed by charge and the quantity of the lithium ion reduced on the negative electrode is thus limited. Consequently, a large quantity of lithium ion cannot be continuously reduced. The state where the lithium ion exceeding the reducing performance of the negative electrode migrates to the negative electrode is eliminated, the negative electrode is made into the more minute state, and activated lithium is hardly generated. |
