Sodium titanates were found as impressive anode materials for sodium-ion batteries (SIBs) because of its low working potential, high energy density and cost effectiveness. However, the major obstacle is low conductivity, which limits the improvement in electrochemical performances. In this report, based on the high conductivity and large surface area of reduced graphene oxide (rGO), a nanocomposite of sodium titanate integrated with rGO nanosheets (Na2Ti6O13/rGO) was fabricated through a facile solvothermal method and further employed as an anode for SIBs. In order to avoid the sluggish movement of sodium ions, the rGO nanosheets act as electrically conductive paths and facilitate the intercalation/de-intercalation of Na+ ions. In comparison to bare sodium titanate, the Na2Ti6O13/rGO nanocomposite electrode showed the enhanced rate performances, high capacity and an excellent long-range cycling stability, demonstrating the superiority of this unique nanostructure.
