ABSTRACT:
An improved active electrode material for use in pressed nickel electrodes is made by first chemically co-oxidizing nickel and cobalt salts in an aqueous alkaline medium to form the respective NiO.sub.x and CoO.sub.x compounds and thereafter co-precipitating the latter compounds. After the co-precipitated NiO.sub.x and CoO.sub.x compounds are recovered, they are combined with a binder (and other electrode constituents if desired) and pressed into an apertured current collector at elevated pressures to form the pressed nickel electrodes.
