为了改善CeMg₁₀Ni₂合金的电化学储氢性能，快淬技术被用来制备具有非晶纳米晶结构的CeMg₁₀Ni₂合金. 运用X射线衍射及高分辨透射电镜对合金的微观结构及其相组成进行分析. 通过恒电流充放电、高倍率放电、交流阻抗以及动电位极化测试对合金的电化学性能进行了详细研究. 研究结果表明，铸态合金由多相结构组成，经过快速凝固处理的合金内部含有大量的非晶纳米晶结构，而且增加的凝固速度可以增强合金内部的非晶纳米晶形成能力. 快速凝固处理减小了合金的热力学参数（ΔH和ΔS），降低了合金氢化物的热稳定性，改善了电化学放电容量. 另外，快速凝固处理显著改善了合金的电化学动力学性能，合金的表观活化能变化进一步解释了这一结论.

In order to improve the electrochemical hydrogen storage properties of CeMg₁₀Ni₂ alloy, the rapid quenching technology was used to prepare CeMg₁₀Ni₂ alloys with nano-crystalline and amorphous structure. The microstructures of as-cast and as-spinning sample were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The electrochemical hydrogen storage properties were investigated by an automatic galvanostatic charging/discharging, high rate discharging (HRD), electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization techniques. The results revealed that the as-cast alloy was composed of multiphase structures. The as-quenched alloys were made up of nano-crystalline and/or amorphous structures, and the rapid solidification technology enhanced the glass forming ability of alloys. The rapid spinning technology brought on a reduction in thermodynamic parameters (ΔH and ΔS), which lowered the stability of hydride and ameliorated the discharging capacity of alloy sample. Besides, the as-quenched alloys held better electrochemical kinetics, which may be interpreted by the variation of activation energy.
