Synthesis and Characterization of Titania Nanotubes as an Anode material for Lithium-ion Batteries

Titania nanotubes fabricated by potentiostatic anodization of titanium in aqueous solution. Morphology and crystalline structure of titania nanotubes was characterized by field emission scanning electron microscope (FESEM) and energy dispersive X-ray spectroscopy (EDS). The characterizations showed that titania nanotubes well aligned, uniform and impurity free. Electrochemical performances of as-prepared anode were obtained by cyclic voltammetry (CV) and chronopotentiometery (CHP). First charge and discharge capacities are 215mAh/g and 343mAh/g respectively.
