摘要：

Ball-milling Mg2Ni with metallic Ni (70 wt.% vs. Mg2Ni) lead to the formation of a homogeneous amorphous alloy, which exhibited a maximum discharge capacity of ca. 870 mAh g (Mg2Ni)(-1) at 30 degrees C. Its electrochemical and microstructural characteristics indicated that the homogeneous amorphous structure of the alloy was an important factor for such an improvement in charge-discharge characteristics.
