| Abstract: | The La-Mg-Ni system AB_3 hydrogen storage electrode alloys were prepared by induction melting under Ar gas atmosphere.The phase structure and electro chemical properties of these alloys were investigated by means of XRD.Sievert instrument and tri-electrode test system.XRD analyses show that these alloys consist of(La,Mg)Ni_3 phase,(La,Mg)_2Ni_7 phase and a little impurity.The results show that maximum storage capacity of the alloys with PuNi_3 structure is much higher than that of LaNi_5 alloys with CaCu_5 structure. |
