Addition of a surface active agent during hydrolysis of vanadium alkoxide allows to slow the gelification rate and to control the viscosity of the gel. Furthermore, after the surfactant elimination, the porosity of V2O5greatly increases. Consequently, the electrochemical specific capacity and the specific energy increase. Lithium is intercaled into V2O5films up to a stoichiometry of 2.5 moles Li per mole V2O5(3.5 < V vs Li < 1.9). Diffusivity coefficient of layers containing surfactant is hundred times higher than in classical V2O5xerogel.
