Abstract

PURPOSE:To reduce the expansion as well as the increase in the internal resistance of a nonaqueous battery by adding a given ratio of bismuth sesquioxide to manganese dioxide, before the mixture is subjected to heat treatment at a given temperature to obtain a positive active material for the battery. CONSTITUTION:Manganese dioxide, which is used as a positive active material for a nonaqueous battery such as an organic electrolyte battery, is added with 0.5- 2.0mol% of bismuth sesquioxide having basic property that inactivates the acid catalystic property of hydroxyl groups existing on the surface of the former manganese dioxide, before the mixture is subjected to heat treatment at 300-450 deg.C. Since solid acid due to hydroxyl groups existing on the surface of the former manganese dioxide can be neutralized and inactivated, the battery expansion caused by gas generation can be markedly minimized when the battery is preserved at a high temperature 60 deg.C. Besides, the internal resistance of the battery can be maintained low.
