Anodically prepared TiO2 Micro and Nanostructures as Anode Materials for Lithium-ion Batteries

초록

With increasingly strict requirements for advanced energy storage devices in electric vehicles (EVs) and stationary energy storage systems (EES), the development of lithium-ion batteries (LIBs) with high power density and safety has become an urgent task. Because the performance of LIBs is determined primarily by the physicochemical characteristics of its electrode material, TiO2, owing to its excellent stability, high safety levels, and environmentally friendly properties, has received significant attention as an alternative material for the replacement of commercial carbon-based anode materials. In particular, self-organized TiO2 micro and nanostructures prepared by anodization have been intensively investigated as promising anode materials. In this review, the mechanism for the formation of anodic TiO2 nanotubes and microcones and the parameters that influence their morphology are described. Furthermore, recent developments in anodic TiO2 -based composites as anode electrodes for LIBs to overcome the limitations of low conductivity and specific capacity are summarized.
