Electrospinning Preparation and Electrochemical Properties of BiFeO3 and GdFeO3 Nanofibers for their Potential Lithium-Ion Battery Applications

BiFeO 3 , GdFeO 3 and GdFeO 3 /graphene nanofibers were successfully fabricated by using an electrospinning technique with a simple single needle. Their structure, size and morphology were investigated by x-ray diffraction, scanning electron microscopy, transmission electron microscopy, energy-dispersive spectroscopy, and selected area electron diffraction. The diameters of the BiFeO 3 and GdFeO 3 are 60–70 and 80–170 nm, respectively. The electrochemical properties of the BiFeO 3 , GdFeO 3 , and GdFeO 3 /graphene nanofibers for lithium-ion battery applications were evaluated. The results indicate that the GdFeO 3 /graphene composite shows better electrochemical performance than BiFeO 3 and GdFeO 3 nanofibers.
