摘要
对由两步法 (由机械合金化和烧结两个步骤组成 )制备的Mg2 Ni型储氢合金进行高能球磨处理 ,然后对球磨后的Mg2 Ni合金粉进行化学镀及与AB5型合金进行复合等处理。利用X射线衍射 (XRD)、扫描电镜(SEM)分析了经过处理的材料的微观结构 ,并用模拟电池法测定了该材料的电极性能 ,并讨论了化学镀和与AB5型储氢合金复合等因素对Mg2
High energy ball milling was used to prepare Mg 2Ni based hydrogen storage alloys, which was produced by mechanical alloying and sintering. Then electroless plating and composition with AB 5 hydrogen storage alloys were done to milled alloy particles. The microstructures of Mg 2Ni based hydrogen storage alloys caused by above mentioned methods was characterized by X ray diffraction and SEM analysis. While electrode performance of these materials was determined by the simulated battery test. Based on these results, the effects of the mechanical alloying, the composition with AB 5 hydrogen storage alloys and electroless plating on the electrode capacity of Mg 2Ni hydrogen storage alloys were discussed.
