Abstract
Methods are provided for manufacturing an electrode. In one exemplary embodiment, the method includes the steps of contacting the silver layer with vanadium oxide, and heating the silver layer and vanadium oxide in an oxygen-containing atmosphere to form a silver vanadium oxide layer chemically bonded to the metal substrate.
Claims17
A method for manufacturing an electrode from a metal substrate including a silver layer thereon, the method comprising the steps of:
- oxidizing the silver layer on the metal substrate by subjecting the silver layer to an anodic potential of about one volt;
- contacting the silver layer with vanadium oxide;
- and
- heating the silver layer and vanadium oxide in an oxygen-containing atmosphere to form a silver vanadium oxide layer chemically bonded to the metal substrate.

A method for manufacturing an electrode comprising the steps of:
- forming a silver coating on a metal substrate;
- electrochemically oxidizing the silver coating on the metal substrate by exposing the silver coating to anodic potentials on the order of one volt in a suitable electrolyte;
- contacting the oxidized silver coating with vanadium oxide;
- and
- heating the oxidized silver coating and vanadium oxide in an oxygen-containing atmosphere to thereby cause a chemical reaction therebetween to form a silver vanadium oxide layer.

A method for manufacturing a cathode comprising the steps of:
- oxidizing silver on a metal substrate;
- contacting the oxidized silver with vanadium oxide;
- heating the oxidized silver and vanadium oxide to thereby cause a chemical reaction therebetween to form a silver vanadium oxide layer;
- and
- diffusing at least a portion of the silver vanadium oxide layer into the metal substrate to thereby chemically bond the silver vanadium oxide layer to thereto.
