The Impact of the Vanadium Oxide Addition on the Physicochemical Performance Stability and Intercalation of Lithium Ions of the TiO(2)-rGO-electrode in Lithium Ion Batteries

This work determines the effect of the addition of various amounts of vanadium oxide on the work of a cell built from a hybrid V(x)O(y)-TiO(2)-rGO system in a lithium-ion cell. Moreover, a new method based on solvothermal chemistry is proposed for the creation of a new type of composite material combining reduced graphene, vanadium oxide and crystalline anatase. The satisfactory electrochemical properties of VxOy-TiO(2)-rGO hybrids can be attributed to the perfect matching of the morphology and structure of VxOy-TiO(2) and rGO. In addition, it is also responsible for the partial transfer of electrons from rGO to VxOy-TiO(2), which increases the synergistic interaction of the VxOy-TiO(2)-rGO hybrid to the reversible storage of lithium. In addition a full cell was created LiFePO(4)/V(x)O(y)-TiO(2)-rGO. The cell showed good cyclability while providing a capacity of 120 mAh g(−1).
