TiO 2 nanostructures have been considered as promising anode materials in a new generation of lithiumion batteries due to their high safety, superior rate capability and excellent cyclic stability. In particular, TiO 2 mesocrystals, a new class of superstructured materials, have attracted a great deal of research interests due to the unique structure composed of crystallographically oriented nanocrystals, and thus showed improved lithium‐ion insertion performance. In this review, recent progress in preparation and lithium‐ion storage properties of TiO 2 mesocrystals are summarized. Two typical ways for synthesizing TiO 2 mesocrystals are described, namely, the oriented topotactic transformation and direct synthesis in solution. The additive‐free synthesis of TiO 2 mesocrystals and their lithium‐ion intercalation properties are highlighted and discussed.
