Self‐assembled TiO 2 ‐B nanosheets have been successfully synthesized by a rapid, one‐pot, ionic‐liquid‐assisted solvothermal route under microwave irritation. By adjusting the reaction temperature, reaction time, and reactant concentration, the morphology and phase of the as‐formed TiO 2 ‐B nanostructures can be tailored. The unique role of the ionic liquid in the formation of self‐assembled TiO 2 nanosheets has been investigated in detail, and a plausible growth mechanism has been proposed. Owing to the synergetic superiority of hierarchical porosity, a fast pseudocapacitive reaction, and large surface area, the electrode prepared from the self‐assembled porous TiO 2 ‐B nanostructures exhibits high reversible capacity, excellent cyclability, and superior rate capability. The synthetic procedure is simple, efficient, and scalable for mass production. Therefore the as‐formed self‐assembled TiO 2 ‐B nanosheets may offer great potential for next‐generation rechargeable batteries with high‐power densities, and are flexible building blocks for advanced functional devices.
