Abstract

PURPOSE:To flatten the discharge characteristic of a battery, which contains both lithium used as a negative active material and manganese dioxide used as a positive active material, by treating the positive mixture subjected to heat treatment under a reduced pressure while heating it, before the positive mixture is used for assembling the battery. CONSTITUTION:An organic electrolyte battery includes a lithium 3 used as a negative active material, and a positive mixture 5 which is prepared by treating manganese dioxide and is used as a positive active material. The positive mixture 5, before it is used for assembling the battery, is subjected to heat treatment at 250- 450 deg.C, and is treated under a reduced pressure for 4 to 50 hours while being heated at below 200 deg.C. As a result, since the reaction products developed by the reaction between graphite and manganese dioxide during the heat treatment of the positive mixture 5 can be eliminated, the battery can provide a flat discharge characteristic of below 3.2V from the initial stage of the discharge. Besides, the increase in the internal resistance of the battery caused during the preservation can be reduced to a large extent.
