In-situ Deposition Route Synthesis of Graphene Oxide-Sulfur Composites as Rechargeable Lithium-Sulfur Battery Cathode
Journal Title: Scholars Journal of Engineering and Technology - Year 2014, Vol 2, Issue 6
Abstract
was served as a source of sulfur, and graphene oxide-sulfur composites were synthesized by liquid phase in-situ deposition method. In order to observe surface morphology, phase structure and electrochemical properties of the composites, the prepared products had been characterized by X-ray diffraction (XRD), fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy(SEM), charge-discharge measurements and electrochemical impedance spectroscopy(EIS). Comparing properties of composites synthesized by liquid phase in-situ deposition method and conventional method, the results showed that the former exhibited better crystal structure, more successful combination between sulfur and graphene oxide and good electrochemical performance. The in-situ composite was with first discharge capacity of 589mAh/g at the current density of 50mA/g, maintaining 241mAh/g after 20 cycles. And the reversible capacity retention was 40.9%.
