PVPxV2O5 (x = 0, 0.5 and 1) nanobelts were obtained using a simple hydrothermal process from V2O5 xerogel. The structure and morphology of the samples were characterized by X-ray diffractometry (XRD) and scanning electron microscopy (SEM). The interaction between the poly (vinyl pyrrolidone) (PVP) and V2O5 xerogel in the nanocomposites was verified by Fourier transformation infrared spectroscopy (FTIR). The electrochemical cells, with a configuration Li/(LiPF6 + EC + DMC)/(V2O5 + PVP), were fabricated and their electrochemical performance was studied.
