Abstract

Abstract: In this article, the vanadium pentoxide sols are synthesized by two different routes (melted and quenched in oxygen atmosphere or in air). The structure and properties of the vanadium pentoxide xerogel films are characterized by XRD, ESR, cyclic voltammograms curves and UV-visible transmittance analysis. The results show that the sample prepared in oxygen has poorer crystallization, lower content of V4+ ions and higher Li+ insertion capacity compared with that prepared in air.

Key words: Preparation atmosphere, V2O5, Structure, Properties
