Effect of Content of Mg on the Electrochemical Performance of La1-xMgxNi2.8Co0.7 (x=0.1,0.3,0.5) Hydrogen Storage Alloy

摘要：

La1-xMgxNi2.8Co0.7 (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 La2Ni7 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.
