Abstract
The honeycomb-like porous TiO2/graphenes (TiO2/GNs) nanocomposite was prepared by a reflux method. SEM and TEM results showed that nanosized anatase TiO2 (about 5~10 nm) were dispersed uniformly on the surface of the GNs. The TiO2/GNs composite showed excellent rate and cycling performance: A stable charge capacity of 169.5 mAh?g-1 was obtained at 30C, and can restore to 241.7 mAh?g-1 while current went back to 1C. The stable charge capacity of TiO2/GNs nanocomposite electrode up to 201.9 mAh?g-1 was achieved at 10C in the first cycle, and could be maintained at 181.4 mAh?g-1 after 300 times of cycling.
