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.
