Abstract 1. A METHOD FOR THE ELECTRODEPOSITION OF MANGANESE DIOXIDE WHICH COMPRISES: PRETREATING A TITANIUM ANODE BY PROVIDING AN AQUEOUS ELECTROLYTE CONTAINING AT LEAST 25 GM./L. FLUORIDE IONS AND FROM ABOUT 800 TO 1200 GM./L. OF AT LEAST ONE OTHER COMPOUND SELECTED FROM THE GROUP CONSISTING OF ACETIC ACID, ETHYLENE GLYCOL AND A MIXTURE OF NITRIC ACID AND PHOSPHORIC ACID; PLACING SAID TITANIC ANODE IN CONTACT WITH SAID ELECTROLYTE; PLACING A CATHODE IN CONTACT WITH SAID ELECTROLYTE; ELECTROLYZING SAID ELECTROLYTE AT AN ANODIC CURRENT DENSITY OF AT LEAST 10 AMPS/FT,2; PLACING THE TREATED TITANIUM ANODE IN AN ELECTROLYTIC CELL FOR THE ELECTRODEPOSITION OF MANGANESE, SAID CELL CONTAINING AN ELECTROLYTE COMPRISING AN AQUEOUS SOLUTIONS OF MANGANOUS ION IN A CONCENTRATION OF FROM ABOUT 15 TO 50 GM./L. AND FROM ABOUT 10 TO 25 GM./L. SULFURIC ACID, EFFECTING THE ELECTRODEPOSITION OF MANGANESE DIOXIDE ON THE ANODE AT AN ANODIC CURRENT DENSITY OF FROM ABOUT 8 TO 25 AMP/FT.2 AND RECOVERING SAID ELECTRODEPOSITED MANGANESE DIOXIDE.
