Paper Title:
Effect of Al Content on Hydrogen Storage Properties of Amorphous Mg1-xAlxNi (x=0, 0.1, 0.2, 0.3) Alloy
  Abstract

In this paper,the influence of adding Al on the discharge capacity and cycle stability of amorphous MgNi-based hydrogen storage alloys were investigated. Amorphous Mg1-xAlxNi (x=0, 0.1, 0.2, 0.3) alloy powder was prepared successfully by mechanical alloying (MA). X-ray diffraction (XRD) results show that after ball milling with 15h, MgNi alloy formed completely amorphous phase. But for Mg1-xAlxNi (x=0.1, 0.2, 0.3) alloy, it took 30h. It can be concluded that Al partial substituting Mg would decrease the amorphous phase forming ability of Mg-Ni Based Alloy. The discharge capacities and cycle stabilities of these alloys were tested. Compared with amorphous MgNi alloy, the discharge capacities of Mg1-xAlxNi (x=0.1, 0.2, 0.3) alloy were decreased slightly, but the cycle stabilities were significantly enhanced. Mg0.9Al0.1Ni alloy showed the largest discharge capacity and Mg0.8Al0.2Ni alloy showed the best cycle stability. Over all, ternary Mg0.8Al0.1Ni alloy showed the best synthesis properties.
