摘要:
The properties of La0.45Ce0.2Nd0.2Pr0.15Ni3.55Co0.75 alloy electrode com-pared with those of La0.65Nd0.2Pr0.15Ni3.55Co0.75Mn0.4Al0.3 have been investigated, in addition,the effects of Ce have been disscussed. The La0.65Nd0.2Pr0.15Ni3.55Co0.75Mn0.4 alloy electrodeshows a high discharge capacity and rate capability but low cycling stability. With partial sub-stitution for La by Ce, i.e. the La0.45Ce0.2Nd0.2Pr0.15Ni3.55Co0.75 alloy electrode showsa good cycling stability, which decays only 12% of maximum capacity (310 mA.h.g-1) after 300cycles.
