Rutile TiO₂ Submicroboxes with Superior Lithium Storage Properties

Hollow structures of rutile TiO 2 , and especially with non‐spherical shape, have rarely been reported. Herein, high‐quality rutile TiO 2 submicroboxes have been synthesized by a facile templating method using Fe 2 O 3 submicrocubes as removable templates. Compared to other rutile TiO 2 nanomaterials, the as‐prepared rutile TiO 2 submicroboxes manifest superior lithium storage properties in terms of high specific capacity, long‐term cycling stability, and excellent rate capability.
