Abstract:

Nanostructured titania have been intensively investigated as anode materials of Li-ion batteries for their excellent high rate performance. The size effects of TiO2 polymorphs (mainly rutile, anatase and TiO2-B) on their electrochemical performance and the latest efforts in nanoengineering titania anodes through enhancing their ionic or electronic transportation or both are reviewed in this work. We suppose that micron-or submicron­sized porous structures assembled by TiO2 nanoparticles, nanowires/nanotubes or nanosheets with a high percentage of exposing high reactive facets together with a conductive percolating network are ideal anodes not only for high rate lithium storage but also for high packing densities of the active materials.
