摘要
The effects of La and Mg relative content on the electrochemical performances of La1+xMg2-xNi9(x=0, 0.5, 1.0, 1.5) hydrogen storage alloys were investigated. The crystal structure, hydrogen storage capacities and electrochemical performances of the alloys were evaluated. It was found that increase of La content was favorable to decrease hysteresis of hydrogen absorption/desorption, and La2MgNi9 alloy exhibited higher hydrogen storage capacity and better electrochemical properties than the other three alloys.
