dc.description.abstract | Anatase titania nanorodsinanowires, and TiO2(B) are synthesized via a hydrothermal reaction of commercial TiO2 (P-25) in strong alkaline environment. Surfaces of these products are modified by carbon to improve the electrical conductivity through carbonization of pitch as the carbon source at 700 degrees C for 2 h in an Ar atmosphere. Even after carbon coating, the resultants exhibit the same crystal structure and morphology as confirmed by Rietveld refinement of x-ray diffraction data and transmission electron microscopic observation that the images display thin carbon coating layers on the surfaces of anatase nanorods and nanowires. Although the bare and carbon-coated anatase TiO2 nanorods exhibit stable cycling performance, the high rate performance is highly dependent on the presence of carbon because of high electrical conductivity, similar to 10(-1) S cm(-1), enabling Li+ ion storage even at 30 degrees C (9.9 A g(-1)) approximately 100 mAh (g-TiO2)(-1) for the carbon-coated anatase TiO2 nanorods. Besides, the bare and carbon-coated anatase TiO2 nanowires show poor electrode performances due to their large particle size and high crystallinity causing Li+ insertion into the host structure difficult. It is believed that the conducting carbon coating layers greatly improves the electrochemical property through the improved electrical conductivity and shortened diffusion path. | - |
