Electrochemical charge storage of flowerlike rutile TiO2 nanorods

The resulting flowerlike rutile TiO2 nanorods possessed much higher reversible capacity and cycling stability than that of nanosized rutile TiO2 previously reported in the literatures. The flowerlike rutile TiO2 nanorods exhibited a stabilized charge capacity of 183 mA h g−1 after 30 cycles, and the specific surface area was as high as 94 m2 g−1. The charge capacity, which can be extracted from TiO2 electrode during discharging, was higher than the one consumed for charging.
