Abstract
Thin films of V2O5, especially vanadium oxide films with nano- and micro-structures, perform well as cathode material for Li ion batteries and charge storage devices. Thin films of V2O5 with different porosity were obtained by dip-coating sol-gel technique. V2O5 sols were prepared by dissolution of V2O5 powder in benzyl alcohol and isopropyl alcohol in proper proportion. Optical property and porosity of films were characterized by FTIR and ellipsometer. Electrochemical characterization was recorded by chronopotentiometry(CP) and cyclic voltammetry(CV). Furthermore, the study shows that the porous structures of V2O5 films had an effect on the stability and reversibility of the films.
