Abstract
We studied that hybrid material of metal organic framework, using two different metals (bimetal organic frameworks), containing graphene oxide (GO) as a sulfur immobilizing host was successfully synthesized by hydrothermal reaction. Composites were prepared using ligands of varying ratios to observe the structure properties depending on the amount of ligand used. Field emission scanning electron microscopy (FE-SEM), Fourier Transform Infra-Red Spectroscopy (FT-IR), and X-ray diffraction (XRD) were conducted to determine the morphology and micro-structure of the composite. Electrochemical properties were characterized by cyclic voltammetry (CV) and galvanostatic charge-discharge tests. Based on these study, bimetal organic frameworks showed different morphology by ligand amounts and the enhanced performance for Li-S battery cathode.
