| Abstract: | The properties of La_0.45Ce_0.2Nd_0.2Pr_0.15Ni_3.55Co_0.75 alloy electrode com-pared with those of La_0.65Nd_0.2Pr_0.15Ni_3.55Co_0.75Mn_0.4Al_0.3 have been investigated, in addition,the effects of Ce have been disscussed. The La_0.65Nd_0.2Pr_0.15Ni_3.55Co_0.75Mn_0.4 alloy electrodeshows a high discharge capacity and rate capability but low cycling stability. With partial sub-stitution for La by Ce, i.e. the La_0.45Ce_0.2Nd_0.2Pr_0.15Ni_3.55Co_0.75 alloy electrode showsa good cycling stability, which decays only 12% of maximum capacity (310 mA.h.g-1) after 300cycles. |
