Abstract
While the synthesis of TiO<sub>2</sub> hollow structures is wellestablished, in most cases it is particularly difficult to control the crystallization of TiO<sub>2</sub> in solution or by calcination. As a result, TiO<sub>2</sub> hollow structures do not really exhibit enhanced lithium storage properties. Herein, we report a simple and costeffective template-assisted method to synthesize anatase TiO<sub>2</sub> hollow spheres composed of highly crystalline nanocrystals, in which carbonaceous (C) spheres are chosen as the removable template. The release of gaseous species from the combustion of C spheres may inhibit the growth of TiO<sub>2</sub> crystallites so that instead small TiO<sub>2</sub> nanocrystals are generated. The small size and high crystallinity of primary TiO<sub>2</sub> nanoparticles and the high structural integrity of the hollow spheres gives rise to significant improvements in the cycling stability and rate performance of the TiO<sub>2</sub> hollow spheres. © 2014 Wiley-VCH Verlag GmbH & Co.
