摘要
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 low-Co type hydrogen storage alloys are prepared by vacuum induction melting. Through X-ray diffraction （XRD） and electrochemistry, systematical study and analysis is made of the elec trochemical performances （maximum discharge capacity, high-rate capability and recycle stability）, the mi crostructure and kinetic characteristics of hydrogen storage alloys.
