摘　　要：为了改善MgNi合金的电化学性能,采用机械合金化法合成了NiB粉末,并将其与MgNi非晶态合金进行复合;对复合产物的充放电性能进行了研究,发现复合改善了合金的循环稳定性。NiB的复合比例采用10%为最优。To improve the electrochemical characteristics of MgNi alloy, NiB powder was prepared by mechanical alloying method and composed with MgNi amorphous alloy. The charge-discharge performance of the composite was studied. The improvement of cycle stability was ascribed to the composite process, The best ratio of NiB for the composite should be 10%.
