초록
we successfully synthesized TiO₂-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 TiO₂-Ag composite nanowires exhibit superior electrochemical properties when compared to the single TiO₂nanowires and TiO₂nanoparticles (P25, Degussa). Therefore, the results indicate that the introduction of Ag nanophases within the electrospun TiO2 nanowires could be improved the capacitance and cycleability of electrodes in Li-ion batteries.
