| 摘 要： | 采用机械合金化（ＭＡ）方法制备了ＭｇＮｉｘ（ｘ＝０．５，１．０，１．２５，１．５，２．０）二元贮氢合金。并详细研究了含Ｎｉ量对ＭＡＭｇ－Ｎｉ系二元合金结构和电化学性能的影响。结果表明，当ｘ＝０．５时，ＭＡＭｇＮｉ０．５仍为晶态合金。 形成非晶态结构，且放电容量很低；当ｘ＝１．０～２．０时，ＭＡ Ｍｇ－Ｎｉ二元合金可形成非晶相，且非昌Ｍｇ－Ｎｉ二 合金具有较高的室温放电容量。， 时，在非 组成范围内

| Abstract: | MgNi x(x=0 5,1 0,1 25,1 5,2 0)binary alloys have been synthesized using mechanical alloying(MA). The effect of nickel on the structure and electrochemical properties of MA Mg Ni binary alloys has been investigated. All MA MgNi x(x=1 0,1 25,1 5,2 0) alloys, except MgNi 0 5 are amorphous. The properties of the amorphous alloys are better than those of the crystallite one. As the nickel content in amorphous alloys increases, the maximum discharge capacity decreases and the average potential moves towards negative direction, but the decay of charge discharge capacity decreases. |
