Abstract Elemental powders consisted of chemical composition of Ti<inf>49</inf>Zr<inf>26</inf>Ni<inf>25-x</inf>Pd<inf>x</inf> (x = 0, 1, 3, 6) were mechanically alloyed and annealed subsequently, and the discharge performance of the electrodes was measured by a three-electrode cell at room temperature. The annealing after mechanical alloying caused a formation of the icosahedral quasicrystal phase with a Ti<inf>2</inf>Ni type crystal, C14 Laves and α-Ti/Zr phases. The quasilattice constant increased with increasing amount of Pd substituted for Ni up to 3 at.% due to difference in atomic radius between Pd and Ni. The maximum discharge capacity achieved was about 220 mA h/g from a (Ti<inf>49</inf>Zr<inf>26</inf>Ni<inf>22</inf>Pd<inf>3</inf>) electrode at the first discharge process.
