METHOD OF MAKING A PRESSED NICKEL ELECTRODE

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 NiOx and CoOx compounds and thereafter co-precipitating the latter compounds. After the co-precipitated NiO...

Zusammenfassung:	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 NiOx and CoOx compounds and thereafter co-precipitating the latter compounds. After the co-precipitated NiOx and CoOx 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.
