An electrocatalytic cathode that will allow hydrogen peroxide, H202, to behave electrochemically within an Al-H202 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.
