ABSTRACT:
A nickel electrode for an alkaline battery comprises a porous alkaline-proof metal fiber substrate used as a current collector, and active material for the electrode. The active material includes nickel hydroxide powder active material, to which zinc or magnesium is added at a rate in a range of [3]1-10 wt % or 1-3 wt %, respectively. The zinc and magnesium is in a solid solution in crystal of the nickel hydroxide, and the active material forms principle compound of paste, which is loaded in the electrode.
