Paper Title:
Crystallographic and Electrochemical Characteristics of Melt-Spun Ti45Zr30Ni25RE3 (Y, La) Alloys
  Abstract

Ti45Zr30Ni25RE3 (Y, La) alloys were prepared by melt-spun at wheel velocities of 20 m s–1. Ti45Zr30Ni25 and Ti45Zr30Ni25La3 were composed of I-phase, amorphous and Laves phases. Ti45Zr30Ni25Y3 consisted of amorphous phase and I-phase. The addition of La and Y caused the decrease of maximum discharge capacity and the increase of cycling stability, which should be ascribed to the change of various phase abundant. The high-rate dischargeability of Ti45Zr30Ni25 alloy electrode was better than that of Ti45Zr30Ni25Y3 and Ti45Zr30Ni25La3 alloy electrode, which was attributed to the better electrochemical kinetics.
