Abstract:<\/h4>\n
We report results on the electrochemical performance of flexible and binder-free \u03b1-Fe2O3\/TiO2\/carbon composite fiber anodes for lithium-ion batteries (LIBs). The composite fibers were produced via centrifugal spinning and subsequent thermal processing. The fibers were prepared from a precursor solution containing PVP\/iron (III) acetylacetonate\/titanium (IV) butoxide\/ethanol\/acetic acid followed by oxidation at 200 \u00b0C in air and then carbonization at 550 \u00b0C under flowing argon. The morphology and structure of the composite fibers were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), and thermogravimetric analysis (TGA). These ternary composite fiber anodes showed an improved electrochemical performance compared to the pristine TiO2\/C and \u03b1-Fe2O3\/C composite fiber electrodes. The \u03b1-Fe2O3\/TiO2\/C composite fibers also showed a superior cycling performance with a specific capacity of 340 mAh g\u22121 after 100 cycles at a current density of 100 mA g\u22121, compared to 61 mAh g\u22121 and 121 mAh g\u22121 for TiO2\/C and \u03b1-Fe2O3\/C composite electrodes, respectively. The improved electrochemical performance and the simple processing of these metal oxide\/carbon composite fibers make them promising candidates for the next generation and cost-effective flexible binder-free anodes for LIBs.<\/p>\n","protected":false},"excerpt":{"rendered":"
