Electrochemical Performance of V₂O₅ Nano-Porous Aerogel Film

Abstract:

Nano-porous V2O5 aerogel films were prepared by dip-coating vanadium oxide sol onto ITO substrate, using V2O5 powder, Benz alcohol, Isopropanol as precursor materials. The nano pores were characterized by scaning electron microscope (SEM). The electrochemical properties were investigated by chronopotenyiometry(CP) and cyclic voltammograms(CV). Results showed that this porous V2O5 aerogel film exhibited good cycling stability with initial discharge capacity of 143mAh/g and 128 mAh/g after 18 cycles, staying 89.5 % of the initial discharge capacity, at a charge/discharge current density of 200 mA/g.
