Abstract: This invention discloses a method to make a positive electrode and the nickel hydride battery using same. The positive electrode at least comprises a nickel hydroxide plus 1-15 wt. % of fine additive powders selected from the group consisting of Co/CoO, Ni, Cu, Zn, ZnO, C, Mg, Al, Mn, silver oxide, hydride, conductive polymer, and combinations thereof. Said positive electrode further comprises one, two or more additives, 0.01-10 wt. %, selected from the group of MgCl2, CaCl2, SrCl2, SrF2, BaCl2, BaF2, MgF2, and other fluorides/chlorides of alkali metals, alkaline earth metals, Al, Y, Sn, Sb, Ag, transition metals, rare earth metals, and composite metal oxide/halide to improve the performance of said positive electrode at high temperature.
