To meet the requirement of high-performance lithium ion batteries, transition metal oxides have been taken into considerable account to take the place of the commercialized anode material, graphite, which fails to reach a high capacity and satisfactory cycle life in long-term usage. In this study, TiO2 nanosheet arrays, suffering very little volume changes upon lithium ion intercalation/deintercalation, were synthesized through a facile hydrothermal method as a stable backbone for subsequent chemical bath deposition of interconnected mesoporous...
