| 摘 要： | 采用机械合金化法合成了NiB粉末，并将其与MgNi非晶态合金进行机械复合，研究了复合对MgNi贮氢合金电极结构及电化学性能的影响。XRD结构分析表明MgNi—NiB通过机械复合后形成了均一的非晶相。电化学性能测试表明：NiB的复合虽然使得MgNi合金电极的初始放电容量有所降低，但是大幅度地提高了电极的循环稳定性。

| Abstract: | NiB powder was prepared by mechanically alloying in this paper and was composited mechanically with MgNi amorphous alloy. The effect of NiB on structure and electrochemical performance of MgNi-electrode was studied. The XRD analysis show that MgNi-NiB composite is amorphous phase. The electrochemical characteristics of this composite were also studied. The cycle life of the MgNi-NiB electrode is improved. |
