Abstract:
An electrolysis process for manufacture of manganese dioxide comprising the steps of:(a) forming an electrolysis system comprising an anode, a cathode, and an electrolysis bath comprising a solution comprising manganese sulfate (MnSO4), sulfuric acid (H2SO4), water, and (b) heating said bath to a temperature above 110Â° C., (c) subjecting said bath to electrolysis while maintaining said bath at above 1100 C, and at a current density of between 12.5 and 37 Amp/ft2 (135 Amp/m2 and 400 Amp/m2) of anode surface area, thereby forming manganese dioxide product and hydrogen gas byproduct.
