摘要

Electrochemical properties of TiO₂ hollow microspheres from a green and template-free route were investigated by charge–discharge, cyclic voltammograms, cycle performance, and high rate capacities measurements. The storage capacity of Li ions in the first discharge process was 290.3 mAh g⁻¹. During the successive 10 cycles, the reversible capacity stayed in the range from 290 to 130 mAh g⁻¹ with a capacity fading of 8.96%per cycle. Cyclic voltammograms measurement exhibited only a pair of reduction/oxidation peaks, indicating TiO₂ hollow microspheres with a good crystalline quality was approached in this route.
