采用真空感应熔炼方法,制备了一系列Cu掺杂的MI(NiCoMnAlCu)5.0即AB5.0型贮氢合金。通过电化学及X射线衍射等手段,系统地研究和分析了Cu掺杂对AB5.0型贮氢合金的电化学性能(最大放电比容量、高倍率性能和循环稳定性能)及其微结构和动力学特征的影响。
A series of Cu-doped MI (NiCoMnAlCu) 5.0 (AB5.0) hydrogen storage alloys were prepared by vacuum induction melting method. The electrochemical properties (maximum discharge specific capacity, high rate capability and cycle stability) of Cu-doped AB5.0 hydrogen storage alloy and its microstructure and properties were investigated systematically by means of electrochemical and X-ray diffraction. Effect of kinetic characteristics.
