Abstract

Mesoporous TiO2 was prepared via a sol-gel method from an ethylene glycol-based titanium-precursor in the presence of a non-ionic surfactant at pH 2. Only the anatase structure was detected after annealing, while the BET specific surface area was measured as being 90 m2 g-1 with a rather monomodal pore diameter close to 5 nm. Electrochemical performances were investigated by cyclic voltammetry and galvanostatic techniques. Mesoporous TiO2 exhibits excellent rate capability (184 mAh g-1 at C/5, 158 mAh g-1 at 2C, 127 mAh g-1 at 6C, and 95 mAh g-1 at 30C) and good cycling stability.
