摘要：

In order to reveal the principle for the effects of rare earth component on the electrochemical properties of AB5 typed alloy, six series of RE (Ni,Co,Mn,Ti)5 alloys of two main element in mishmetal La, Ce, Pr or Nd as its A side element of AB5 typed hydrogen storage alloy were prepared and the effects of variation in A side element were systematically studied. The general formulae may be expressed as A1-αA'αB5, where the A1-αA'α denotes LaαPr1-α,Ceα'Pr1-α', Laα"Ce1-α",or CeβNd1-β(0 ≤ α,α',α",β ≤ 1) and Bis Ni1-a-b-cCoaMnbTic. It's found that, with the same specific 4f electronic concentration, the variation of discharge capacity is quite similar.

The general formulae may be expressed as A1-αA'αB5, where the A1-αA'α denotes LaαPr1-α,Ceα'Pr1-α', Laα"Ce1-α",or CeβNd1-β(0 ≤ α,α',α",β ≤ 1) and Bis Ni1-a-b-cCoaMnbTic. It's found that, with the same specific 4f electronic concentration, the variation of discharge capacity is quite similar.
