Abstract

Abstract:

Y_1-_xLa_xNi_3.25Al_0.15Mn_0.15 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,C_max,S₁₀₀,D₀ and HRD₉₀₀ of hydrogen storage alloy increased at first and then decreased,and the maximum values of C_max,S₁₀₀,D₀ and HRD₉₀₀ were obtained at x=0.33.The cycle stability of Y_1-_xLa_xNi_3.25Al_0.15Mn_0.15 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.

Key words: hydrogen storage alloy, new energy vehicle, battery, electrochemical performance
