Abstract
A fabrication method for a paste-type metal hydride electrode for a nickel/metal hydride battery which includes; pulverizing a V-Ti-Zr-Ni-type and Mm-type hydrogen storage alloy in which a small amount of Pd and/or Ru are combined; mixing K.B.(or Ni powder)+PTFE+CMC(HPMC) undiluted paste solution with the hydrogen storage alloy powder, filling a porous nickel with the mixed paste, drying the paste-filled porous nickel, and press-forming the dried paste and which, by providing the paste-type electrode fabrication, is capable of not lowering the electrode capacity by preventing the oxidation of active material and poor conductivity and has the effect of a preventing significant decrease of the electrode capacity, a remarkable increase in cycle life of electrode, and the realization of a paste-type fabrication of an AB.sub.2 type alloy in accordance with a new paste composition and hydrogen storage alloy composition, which has previously been regarded as impossible.
