TiO2-B nanofibers with high thermal stability as improved anodes for lithium ion batteries

TiO2-B nanofibers with large surface area, high thermal stability and high crystallinity were synthesized by steam thermal method from K2Ti2O5. Compared to the bulk TiO2-B (TB-bulk) prepared from K2Ti4O9, these nanofibers exhibited much higher reversible capacity, cycling stability and rate capability. Such excellent electrochemical performances were derived from the facile charge transport due to the specific framework of a large specific surface area and one dimensional structure.

► We prepared TiO2-B nanofibers utilizing a very simple methodology.
► The nanofibers exhibit a large specific surface area of 112 m2 g− 1.
► The nanofibers possess high crystallinity and thermal stability until 600 °C.
► The TiO2-B electrodes show excellent rate capability and cycling stability.
► This material can be considered as an alternative anode material.
