【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。更多还原

【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.更多还原
