Popis:	Herein, the composite of vanadium pentoxide and graphene oxide (V2O5/GO) was synthesized by the solgel method. The synthesized composite V2O5/GO was characterized by X-Ray diffraction analysis and Raman spectroscopy. After in situ reduction of GO, the electrochemical characteristics of V2O5/rGO were analyzed by cyclic voltammetry in Mg(NO3)2 aqueous solutions. The V2O5/rGO composite showed following intercalation capacities: initially 139.1 mA h g-1 and 101.8 mA h g-1 after the 10th cycle, which along with easy, fast and low-cost synthesis, make this composite a potentially good electrode material for application in secondary aqueous magnesium-ion batteries.
