We synthesized both the V_{2}O_{5} xerogel and the composite V_{2}O_{5} xerogel/C starting from the solution of V_{2}O_{5} in hydrogen peroxide. After the characterization by XRD, thermal (TGA-DTA), SEM methods and by particle size analysis, the investigation of Li^{+} and Mg^{2+} intercalation/deintercalation reactions in an aqueous solutions of LiNO_{3} and Mg(NO_{3})_{2} were performed by cyclic voltammetry. The composite material V_{2}O_{5} xerogel/C displayed relatively high intercalation capacity, amounting to 123 mA h g^{-1} and 107 mA h g^{-1}, in lithium and magnesium salt solutions, respectively.
