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