Résumé     
The formation of the xerogel precursor of Li1+alphaV3O8 within a suspension of carbon black allows the synthesis of Li1+alpha+xV3O8/beta-Li1/3V2O5/C nanocomposites upon heating under argon at 350 degrees C for a few minutes. The intimate contact of the active material with carbon particles ensures a limitation of the particle growth, a reduction-insertion of the pristine Li1+alphaV3O8 compound along with the formation of beta-Li1/3V2O5, and an efficient electronic transport to the active materials. The electrochemical performance of these nanocomposites is significantly better in terms of both initial capacity and capacity retention upon cycling than that of standard Li1+alphaV3O8.
