| Abstract | The lithium intercalation properties of anatase TiO2 electrodes with a bimodal pore size distribution were examined. Porous anatase TiO2 was prepared by hydrolyzing titanium tetrabutoxide using polyoxietylene cetyl ether as a surfactant and its subsequent calcination at 500°C for 4 hours. A porous anatase TiO2 electrode with a relatively large pore volume and 50-nm-diamater pores showed a discharge capacity of approximately 150 mAh g-1. It maintained a relatively large discharge capacity of 125 mAh g-1 at a current density of 1 A g-1, and exhibited a good high-rate capability. |
