Abstract
ELECTROCHEMICALLY PREPARED (EP) SILVER OXIDE HAS BEEN USED IN PRIMARY RESERVE ZN-SILVER OXIDE BATTERIES BECAUSE OF IT HIGH RATE DISCHARGE CAPABILITY. HOWEVER, THE EP SILVER OXIDE IS THERMALLY UNSTABLE UNDER STORAGE THUS LIMITING THE SHELF LIFE OF THE ZN-AGO BATTERIES AND FORCING MANUFACTURERS TO PERIODICALLY REPLACE THOSE BATTERIES AT GREAT EXPENSE. WE PROPOSE TO DEVELOP A NEW ANODIZATION OF SILVER PLATES FOR MAKING HIGH PURITY AND THEMALLY STABLE ELECTROCHEMICALLY PREPARED SILVER OXIDE (AGO). TO INDUCE THE FORMATION OF PERFECT AGO LATTICE WHICH IS THERMALLY STABLE, WE PROPOSE TO PROCEED THE ANODIZATION AT HIGH TEMPERATURE INSIDE AN AUTOCLAVE SO THAT TEMPERATURE ABOVE THE BOILING POINT OF THE ELECTROLYTE CAN BE REACHED AND TO APPLY REVERSE PULSE ANODIZATION INSTEAD OF STRAIGHT CURRENT ANODIZATION FOR INCREASING THE EFFICIENCY AND QUALITY OF THE AGO FORMATION.
