The electrode alloys Mg2-xZrxNi (x = 0; 0.15; 0.3; 0.45 and 0.6) were prepared by mechanical alloying (MA). Mg in the alloy was partially substituted with Zr in order to improve the electrochemical characteristics of the Mg2Ni-type alloy. The microstructures and the electrochemical characteristics of the experimental alloys were measured systemically. The effects of substituting Mg with Zr and MA technique on the microstructures and electrochemical performances of the alloys were investigated in detail. The results obtained by XRD; SEM and TEM show that the substitution of Zr is favourable for the formation of an amorphous phase. For a fixed milling time; the amorphous phase in the alloy grows with increasing Zr content. The electrochemical measurement indicates that the substitution of Zr can dramatically enhance the discharge capacity with preferable cycle stability; and it markedly improves the discharge voltage characteristic of the alloys. For x &le 0.3; the discharge capacity of the alloys monotonically increases with milling time. But for x > 0.3; it has a maximum value with the change of milling time. © 2006 Elsevier B.V.
