PURPOSE:To produce the electrolytic manganese dioxide having high performance by using a soln. of manganese sulfate and sulfuric acid as an electrolyte and adding a reducing agent or nonionic surfactant into the electrolyte. CONSTITUTION:An electrolysis is effected by using the manganese sulfate and sulfuric acid soln. as the electrolyte to produce the electrolytic manganese dioxide. The reducing agent and nonionic surfactant are added at about 0.01 to 3.0g/l into this electrolyte. Hydradinium sulfate having an amino group or carboxyl group, and aniline, etc., are used as the reducing agent and ethylene glycol and the condensation product thereof, etc., are used as the nonionic surfactant. The discharge voltage of a manganese battery is improved and the discharge time thereof is prolonged if this electrolytic manganese dioxide is used as the anodic active material of this battery. |
