Although it occurs naturally in manganese ores, manganous dioxide, which finds its principal application as a depolarizer in drycell batteries, is usually produced synthetically. Manganese ore is reduced and then leached with sulfuric acid. The solution is purified, and manganous dioxide is obtained by electrolysis.
This limits its applications. Similarly, MnSO₄ can only be used in batteries, and then it must be sufficiently purified to meet the battery grade specifications. Why Use Manganese in Batteries? "Manganese is ideal for use in batteries due to its natural ionic state.
The present invention relates to a positive electrode mixture for a manganese dry battery. More specifically, the present invention relates to a positive electrode mixture having a composition capable of maximizing the performance of chemically synthesized manganese dioxide in a dry battery of a type called a zinc chloride dry battery.
