Rate Characteristics of Anatase TiO[sub 2] Nanotubes and Nanorods for Lithium Battery Anode Materials at Room Temperature

Anatase nanotubes and nanorods were prepared by annealing mixed and anatase nanotubes at 300 and , respectively. The first discharge capacities of anatase nanotubes and nanorods were and , respectively. Irreversible capacity ratios were 14 and 15% for anatase nanotubes and nanorods, respectively. Capacity retention of the nanotubes was 81%, and that of the nanorods was 40% after . In contrast to nanotubes, the high rate performance of nanorods strongly depended on the electrode density of the electrode. Nanorods with showed 200 and at 0.5 and rates, respectively. However, nanotubes showed no capacity decrease at 0.5 or under an electrode density of either 1 or . Under , nanotubes showed 245 and at 0.5 and rates, respectively.
