Phase structure and electrochemical properties of the storage hydrogen electrode alloys Zr1-xTix(Mn0.7V0.2 Co0.1Ni1.2)were investigated by XRD,SEM and EPMA, and electrochemical properties of the alloys were examined. The matrix alloys consisted of cubic C15 Laves phase and second phase (Zr7M10). With the increasing of Ti content, the lattice parameter of alloys decreased and C14 Laves phase appeared and increased. A little of TiNi phase appeared at x=0.1~0.2; however, Zr7M10 phase and TiNi phase decomposed at x=0.4~0.5, which demonstrated that high Ti content inhibited the appearance of second phase in the alloys. As a result, the storage hydrogen electrode alloy Zr0.8Ti0.2(Mn0.7V0.2Co0.1Ni1.2), the maximum discharge capacity of which is 354 mAh/g, possesses good rate capability. This contributes to change phase structure and phase composition, which plays a synergetic role in the charge-discharge process.
