Herein, we first report a facile synthetic route for preparing micron-sized particles comprising TiO(2)-B nanotubes, namely, skein shaped TiO(2)-B nanotube cluster particles with an ultra high surface area of 257 m(2) g(-1). The galvanostatic charge-discharge test showed that the hierarchical micron-sized particles composed of TiO(2)-B nanotubes with approximately 10 nm in diameter exhibited outstanding rate capability as well as high specific capacity.
