Abstract

LaMgNi₄ ternary alloy was synthesized by sintering pressed tablets of mixed powders of Mg, La and Ni. The sintering condition is: 673K, 3h→873K, 3h→973K, 3h. XRD analysis shows that synthesized LaMgNi ₄ alloy is a single-component alloy, and a laser particle size method was used to measure the particles of the milled LaMgNi₄ alloy. The electrode properties of LaMgNi₄ alloy were measured by simulated battery test. It was found that the initial discharge capacity of the two alloys milled for 50h were about 400mAh/g, but a good cycle life has been observed in the LaMgNi₄ alloy electrode compared with the Mg ₂Ni alloy electrode.
