Abstract

La_1-xMg_xNi_2.8Co_0.7 (x=0.1, 0.3, 0.5) hydrogen storage alloy was synthesized by solid diffusion method. The microstructure of the alloy was analyzed by XRD when the content of Mg was changed. When x equaled to 0.3, there was relative much La₂Ni ₇ phase in the alloy and the alloy exhibited better integrated electrochemical performance. Its maximum discharge capacity reached 355.4mAh/g and capacity retention after 50 cycles(S₅₀) was 77.80%. The results showed the existence of La₂Ni₇ phase would be conductive to the integrated electrochemical performance of the alloy.
