Preparation of an electrocatalytic cathode for an aluminum-hydrogen peroxide battery

Abstract

An electrocatalytic cathode that will allow hydrogen peroxide, H.sub.2 O..2, to behave electrochemically within an Al-H.sub.2 O.sub.2 battery system is provided. The electrocatalytic cathode is comprised of nickel specially coated with one or a combination of the following six metals: platinum, ruthenium, rhodium, osmium, palladium, and iridium. The use of nickel coated with the appropriate combination of metals reduces the problems of excessive peroxide decomposition, thereby producing a battery that can operate efficiently by producing a high voltage at a high current density. The electrocatalytic cathode is produced by pretreating a nickel electrode with a hydrochloric acid bath and then by applying the metal coating by plating methods.
