Lithium-ion batteries (LIBs) are promising energy storage devices for portable electronics, electric vehicles, and power-grid applications. It is desirable to develop a simple and scalable method for constructions of sustainable materials for safe LIBs with high rate performance. Titania has superior safety and better rate performance than graphite, the state-of-the-art anode material for LIBs; however, its electrochemical performance is still hindered by the sluggish Li-ion diffusion and poor electronic conductivity. Herein, we present the synthesis of hydrogen titanate ultrathin nanobelts via a wet-chemistry route at ambient conditions. With the morphology remained stable, the hydrogen titanate can be easily converted to anatase TiO2 by a subsequent calcination. The resultant anatase nanobelts show excellent performances when utilized as an anode for LIBs. Moreover, this synthetic strategy can be used to fabricate TiO2 nano-trees, which demonstrate high areal/volumetric capacities for lithium-ion micro-batteries.
