In summary, VSG composites have been successfully synthesized by a solvothermal reaction. As an anode electrode material for SIBs, because of the synergistic effect between VS4 and rGO, it has a good cycling stability, rate capability and Columbic efficiency compared with pure VS4. At the first cycle, VS4 has a conversion battery reaction from VS4/rGO to Na2S + V/rGO composite. After the first cycle, the battery reaction can be associated with Na-S battery. With the presence of rGO, the

Nanorod vanadium sulfide wrapped by reduced graphene oxide (rGO) composite is synthesized by a facile solvothermal reaction. Nanorod vanadium sulfide is uniformly distributed on the surface of rGO nanosheets. As an anode for sodium ion batteries, the composite with 13 wt% rGO has 1203.8 and 781.4 mAh g−1 specific capacities for the first discharge and charge, respectively, with 64.9% of Coulombic efficiency, higher than that of pure vanadium sulfide submicrospheres. The sodiation/desodiation mechanism is investigated by cyclic voltammetry, ele...
