Abstract: The structure and electrochemical properties of Zr0.9Ti0.1(Ni,Co,Mn,V)2.1 alloys prepared by both the melt-spinning method and the conventional induction melting were investigated. XRD studies showed that Zr0.9Ti0.1(Ni,Co,Mn,V)2.1 alloys at as-cast, melt-spinning and annealing were all the face center cubic structure with Laves C15 phase, and the higher the melt-spinning rate, the more the amorphous content. The electrochemical measurements showed that melt-spinning alloys had better activity, low discharge capacity (<270 mA×h/g); but after annealed, the alloys are activated completely with 30 cycles, the capacities about 340 mA×h/g were higher than those of the as-cast and melt-spinning alloys; the annealed alloys had better cycle stability than that of the as-cast alloy, and the higher the melt-spinning rate, the more stable the alloy became.
