Abstract
Electrolytic manganese dioxide having a BET specific surface area of less than 30 m.sup.2 /g and a suspensiveness of less than 50 mg/liter is used for alkaline manganese batteries and manganese batteries to make them excellent both in initial performance and storability. The electrolytic manganese dioxide may be made by a suspension method or a clarification method.
