The performance of energy storage materials is highly dependent on their nanostructures. Herein, hierarchical rod-in-tube TiO2 with a uniform carbon coating is synthesized as the anode material for sodium-ion batteries by a facile solvothermal method. This unique structure consists of a tunable nanorod core, interstitial hollow spaces, and a functional nanotube shell assembled from two-dimensional nanosheets. By adjusting the types of solvents used and reaction time, the morphologies of TiO2/C composites can be tuned to nanoparticles, microrods, rod-in-tube structures, or microtubes. Among these materials, rod-in-tube TiO2 with a uniform carbon coating shows the highest electronic conductivity, specific surface area (336.4 m2 g-1), and porosity, and these factors lead to the best sodium storage capability. Benefiting from the unique structural features and improved electronic/ionic conductivity, the as-obtained rod-in-tube TiO2/C in coin cell tests exhibits a high discharge capacity of 277.5 and 153.9 mAh g-1 at 50 and 5000 mA g-1, respectively, and almost 100% capacity retention over 14,000 cycles at 5000 mA g-1. In operando high-energy X-ray diffraction further confirms the stable crystal structure of the rod-in-tube TiO2/C during Na+ insertion/extraction. Finally, this work highlights that nanostructure design is an effective strategy to achieve advanced energy storage materials.
