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.

우리는 전기방사법을 이용하여 $TiO_2$-Ag 복합 나노선 전극을 성공적으로 합성 하였으며 그들의 전기화학적 특성 및 구조 사이의 관계를 주사전자현미경(FESEM), 투과전자현미경(TEM), X-선 회절(XRD), X-선 광전자 분광법(XPS) 및 cycler에 의하여 규명하였다. 특히 $TiO_2$-Ag 복합 나노선 전극의 전기화학 특성은 순수한 $TiO_2$ 나노선 전극 및 나노입자(P25, Degussa)와 비교하였을 때 우수한 전기화학적 결과를 얻었다. 따라서 $TiO_2$ 나노선 전극 안에 Ag nanophases의 도입은 리튬이온 배터리를 위한 나노선 전극의 수명 및 용량을 향상 시킬 수 있다.
