Preparation and electrochemical performance of hollow-spherical polypyrrole/V2O5 composite

Journal Article


Abstract


  • In order to improve the lower practical capacity and bad cyclability of crystalline V2O5 (c-V2O5), the vanadium oxide

    (V2O5) and polypyrrole (PPy) hybrid with hollow-spherical(HS) structure was studied. HS nanocomposite comprised of conductive

    polypyrrole and vanadium pentoxide (PPy/V2O5) was synthesized by polymerization of pyrrole monomer (Py) in the

    hollow-microspherical V2O5 host. This novel hybrid was characterized by X-ray diffraction (XRD), scanning electron microscopy

    (SEM), transmission electron microscopy (TEM) and tested as the cathode material for lithium-ion batteries (LIB) by galvanostatic

    cell cycling and electrochemical impedance spectroscopy (EIS). The hollow-spherical polypyrrole/vanadium oxide (HS-PPy/V2O5 )

    composites, in which PPy molecules are intercalated between the layers of V2O5, exhibit slight reduced capacity and substantially

    improve cyclability and electrochemical activity compared with the pure HS-V2O5.
