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. © 2011 The Nonferrous Metals Society of China.
