Abstract

Y1-xLaxNi3.25Al0.15Mn0.15 hydrogen storage alloy(x=0~1) was prepared by vacuum arc melting and annealing at 925 ℃ for 12 h.The effect of x value on the phase composition and electrochemical properties of hydrogen storage alloy was studied.The results showed that hydrogen storage alloys with x=0 and 0.15 were mainly composed of LaNi5 and Ce2Ni7 phases;hydrogen storage alloys with x=0.25,0.33 and 0.5 were mainly composed of Ce5Co19 and Ce2Ni7 phases;hydrogen storage alloys with x=0.75 and 1 were mainly composed of PuNi3,LaNi5 and Ce2Ni7 phases;under the same charge discharge cycle,the discharge capacity and anti hydrogen induced amorphization ability of hydrogen storage alloy with x=0.15~1 were higher than that of hydrogen storage alloy with x=0,and with the increase of x value from 0 to 1,Cmax,S100,D0 and HRD900 of hydrogen storage alloy increased at first and then decreased,and the maximum values of Cmax,S100,D0 and HRD900 were obtained at x=0.33.The cycle stability of Y1-xLaxNi3.25Al0.15Mn0.15 hydrogen storage alloy was closely related to the corrosion resistance of the alloy electrode, and the high rate discharge performance depended on the hydrogen diffusion rate of the hydrogen storage alloy.
