New cathode mixture for the zinc–manganese dioxide cell

A modified zinc–manganese dioxide cell with a new cathodic active mass constitution was investigated. This modification improved all operational parameters of this cell, particularly voltage stability during discharge and increased electrical capacity of the cathode, making it competitive even with the better classified commercial “Heavy Duty” (HD) batteries based on zinc chloride electrolyte. Major benefits of this modification were: an improved voltage stability during discharge and a higher electrical capacity of the cathode.
