In this paper we described an effective approach to optimize titanium dioxide nanowires on titanium substrate-based anodes. TiO2 nanowires were successfully fabricated by electrospinning technique, to be used as anode material for Lithium ion batteries. The Scanning Electron Microscopy (SEM) analysis revealed a multi-layered random network structure with irregular surface. The X-Ray Diffraction (XRD) patterns of TiO2 nanowires calcined exhibited diffraction peaks corresponding to TiO2 in both form of anatase and rutile phase. The obtained TiO2 based electrodes were electrochemically evaluated using a 3 electrode cell configuration in aqueous solution (LiClO4, 0.1 M). The resulted electrodes corresponding to the solution feed-rate of 0.6 mL/h (injection speed 0.0025 mm/min), deposited at 20 kV, and 20 cm has demonstrated to be promising candidates as anode material for Lithium ion batteries. Moreover, it is believed that the optimization of electrospinning parameters for producing TiO2 nanowires can increase the cycling performance and rate capability.
