Abstract

Vanadium pentoxide thin films were produced from organic and inorganic precursors by sal gel dip-coating method. Fourier transform infrared spectroscopy and UV Vis spectroscopy were made to figure out structural properties of the films. Electrochemical properties were investigated by cyclic voltammetry. The shape of the curves was in agreement with a typical diffusion controlled cyclic voltammograms of amorphous V2O5 films for a reversible lithium ion intercalation/deintercalation process showing yellow-green-blue multi-electrochromism. V2O5 films, synthesized from organic precursor, indicated lower band gap energy, higher charge capacity as well as homogeneous and low granule size compared to inorganic route. (C) 2014 Elsevier Ltd.
