Paper Title:
Electrochemical Performance of New Ferroalloy Electrode of RE2FeSb2 (RE = Y, Dy, Er)
  Abstract

Rare earth antimonide stoichiometric compounds RE2FeSb2 (RE=Y, Dy, Er) were prepared and examined by X-ray diffraction technique. XRD analysis showed that these alloys were crystallized in cubic RESb-type structure. The electrochemical properties of these alloys such as discharge capacity and cycling performance were investigated by battery testing instruments in alkaline electrolyte. Electrochemical tests discovered that the alloys RE2FeSb2 (RE=Y, Dy, Er) had two clear and wide discharge potential ranges. Furthermore, the first charge and discharge cycle showed that the discharge capacities of RE2FeSb2 (RE=Y, Dy, Er) were about 12.8,15.1,16.0 electron/formula, respectively. The ferroalloy electrode of RE2FeSb2 (RE=Y, Dy, Er) had latent superiority in electrochemical properties.
