Vanadium monoxide (VO) nanoparticles and reduced graphene oxide (rGO) composites with a 3D architecture (GVO) was synthetized by a simple hydrothermal reaction of a mixture of vanadium pentoxide (V2O5) ribbons and graphene oxide (GO). It shows large contact area between electrode and electrolyte, short electron and ion diffusion pathways for LIBs and good electrical conduction. As a result, when the GVO was served as the LIBs anode material, the resulting electrodes exhibited a high specific capacity (909 mAh g−1 at 74.4 mA g−1 after 30 cycles) and remarkable cyclic stability.
