Abstract
A zinc-silver oxide dry cell comprises a zinc anode, a silver oxide cathode, an immobilized body interposed between the anode and the cathode, and a metallic silver layer formed at least on the anode side surface of the cathode by reduction of silver oxide. Reduction of the siver oxide to form the metallic cathode layer on the cathode surface is effected by causing a reducing agent to contact with the cathode surface or by subjecting the cathode surface to a heat treatment, electrolysis or a mechanical force.
Claims5
An alkaline dry cell comprising an anode containing zinc as an active ingredient;
- a cathode containing monovalent silver oxide as an active ingredient;
- an immobilized body of an alkaline electrolyte interposed between said anode and said cathode;
- and a metallic silver layer formed at least on the anode side surface of said cathode by reduction of silver oxide, the reduction being effected by causing a reducing agent to contact with the cathode.
