Abstract:
1. An electrochemical cell having an anode, a cathode of electrically conductive material, and an ionically conductive electrolyte activating the anode and the cathode, wherein the electrically conductive material of the cathode is characterized as having been formed by a process consisting essentially of the sequential steps of: a) forming a substantially homogeneous mixture of starting materials comprising a decomposable silver-containing constituent and a vanadium-containing constituent, wherein the homogeneous mixture is formed at a mixing temperature below a decomposition temperature of the mixture of the starting materials; b) heating the homogeneous mixture in an inert atmosphere to effect decomposition and produce a mixed metal oxide intermediate; c) heating the mixed metal oxide intermediate in an oxidizing atmosphere to produce a product mixed metal oxide; and d) contacting the product mixed metal oxide to a cathode current collector to form the cathode.
