摘要：

The LaMg12-based nanocrystalline alloys were prepared by ball-milling as-cast LaMg12 alloy with Ni powders. The electrochemical charging and discharging in KOH solution of the ball-milled LaMg12-based nanocrystalline alloys succeeded due to the formation of the metallic Ni particles highly dispersed through nanocrystalline alloy matrix. The first discharge capacity of the ball-milling LaMg12 alloys with Ni powders in a weight ratio of 1:3 reached up to 1010 mA·h/g.
