The Impact of the Vanadium Oxide Addition on the Physicochemical Performance Stability and Intercalation of Lithium Ions of the TiO-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 VO-TiO-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-rGO hybrids can be attributed to the perfect matching of the morphology and structure of VxOy-TiO and rGO. In addition, it is also responsible for the partial transfer of electrons from rGO to VxOy-TiO, which increases the synergistic interaction of the VxOy-TiO-rGO hybrid to the reversible storage of lithium. In addition a full cell was created LiFePO/VO-TiO-rGO. The cell showed good cyclability while providing a capacity of 120 mAh g-.
