Abstract
we successfully synthesized $TiO_2$-Ag composite nanowires via an electrospinning method and investigated the relationship between their electrochemical properties and structures by means of field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and cycler. It is shown that the $TiO_2$-Ag composite nanowires exhibit superior electrochemical properties when compared to the single $TiO_2$ nanowires and $TiO_2$ nanoparticles (P25, Degussa). Therefore, the results indicate that the introduction of Ag nanophases within the electrospun $TiO_2$ nanowires could be improved the capacitance and cycleability of electrodes in Li-ion batteries.
