Abstract:
1. A method of manufacturing a nickel electrode for a nickel-zinc battery, comprising the steps of: (a) providing a nickel oxyhydroxide (NiOOH) and a nickel metal; (b) adding a first additive consisting of transition metal oxide to said nickel oxyhydroxide and said nickel metal; and (c) adding a binder for combining said first additive to said nickel oxyhydroxide and said nickel metal, wherein said first additive contains one or more transition metal oxides selected from a group consisting of ruthenium oxide (RuO wherein the step (b) further comprises the step of: (b.1) adding a second additive consisting of (i) a metal oxide with one or more rare earth oxides or (ii) a metal hydroxide with one or more rare earth oxides to said nickel oxyhydroxide and said nickel metal to increase an electrode capacity and a shelf life of said nickel electrode, wherein said binder combines said first additive and said second additive to said nickel oxyhydroxide and said nickel metal; and (b.2) adding a zinc oxide (ZnO) or hydroxide (Zn(OH)
