摘要

以LaMg11Zr为母体合金,由机械合金化方法制备LaMg11Zr+200%N i合金,用X射线衍射(XRD)测定球磨时间对非晶相化的影响,20 h合金即可达到完全非晶态化,合金电极化学性能和循环寿命最好.

Abstract

Using the LaMg11Zr as the initial alloy,the LaMg11Zr+Ni composite was prepared by mechanical alloying,and the effect of ball-milling time on the amorphous structure of alloy powers was characterized by X-ray diffraction(XRD).The amorphous(LaMg11Zr+Ni) alloy can be obtained after 20 h ball-milling,and has the best electrochemical capacity,electrochemical cycle stability.

Key words： La-Mg series hydrogen storage alloy; mechanical alloying; electrochemical capacity
