Titanium dioxide – based fiber anodes and their potential use in CR2032 coin cell lithium batteries 

Abstract

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.
