Hydrothermal synthesis of TiO2(B) nanowires with ultrahigh surface area and their fast charging and discharging properties in Li-ion batteries

Abstract

We first report a facile hydrothermal route for preparing TiO₂(B) nanowires with ultrahigh surface area, up to 210 m² g⁻¹. Due to the 1D structure, high BET surface area and shorter b-and c-axis channel across the nanowires, the obtained TiO₂(B) nanowire was shown to be a good anode material for lithium-ion batteries, especially on the fast charging and discharging performance.
