Consequently, the improvement of cycle life is described as the partial substitution of Zr for Mg in the alloy.

XRD结构分析表明：主相仍为Mg↓2Ni； Zr替代Mg使合金的微晶结构发生了改变，趋于非晶化；添加Zr的合金的容量比由扩散法合成的合金的容量有所提高；合金中添加Zr，提高了电极的放电容量，增大了放电平台；特别是Zr 对六方晶系Mg2Ni合金结构中Mg的部分取代大幅度提高了电极的循环寿命，未经任何处理的 Mg1.4Zr0.6Ni合金电极经25个循环后，放电容量仅衰减4.11%，表明添加Zr对提高合金的循环寿命具有重要的作用。
