Fabrication of TiO2 hollow nanostructures and their application in Lithium ion batteries

A facile hydrothermal route is used for the synthesis of TiO2 hollow nanostructures. The choice of LiOH plays an important role in the formation of TiO2 hollow nanocrystals. XRD and HRTEM patterns show that TiO2 hollow nanostructures are anatase and TiO2 (B) structure. The electrochemical performance measurement demonstrated that the as-prepared TiO2 hollow nanostructures exhibit good lithium storage performance and excellent cyclability (which delivers a higher reversible capacity of 227 mAhg(-1) at 0.5 C after 100 cycles). The unique architecture should be responsible for the superior electrochemical performance. (C) 2015 Elsevier B.V. All rights reserved.
