Seven multiphase YNi3 and YN4 based alloys have been prepared by arc-melting. Based on X-ray phase and structural analysis synthesized alloys depending on its composition contain intermetallics with PuNi3, Gd2Co7 and CaCu5 structure types. The influence of Y/La and Ni/Co/Mn/Al substitution on the discharge characteristics of the AB3 and AB4 electrodes was studied. Substitution Y by La and further Ni by Mn and Al lead to increasing discharge capacity from 40 to 341 mAh/g. Positive effect of Ni/Co/Al or Ni/Mn/Al substitution was also observed for the AB3 electrodes. The high discharge capacities of 318 mAh/g and 340 mAh/g were seen for the YNi2.65Co0.2Al0.15 and YNi2.65Mn0.2Al0.15 electrodes. |
