Abstract TiO2-B nanobelts have been synthesized by hydrothermal route using TiO2-anatase precursors with different microstructure. The decrease in average size of starting product improves the degree of TiO2-B crystallinity and increases the surface area. Both of them strongly influence on the electrochemical performance of as-prepared TiO2-B: the capacity of 203 mAh g−1 is still maintained after 35 cycles, with a degradation of 0.25% per cycle for material synthesized using TiO2-anatase phase with a particle size of 25 nm. Oppositely, the samples obtained from larger particles show poorer lithium storage with a worse capacity retention.
