Lithium-sulfur batteries are studied for one of next-generation to replace lithium-ion batteries due to their lightness and theoretical capacity. Because of their controllable pore size, highly ordered structure and very high porosity, metal-organic frameworks (MOFs) are studied as sulfur host of lithium-sulfur battery’s cathode. In particular, the increasing number of studies about MOF composite materials as Li-S electrode materials provided reliable results that shows excellent performance. MOF-808@sulfur composite electrode materials were prepared by hydrothermal reaction with using organic ligands and metal ions. The morphology of the composites was examined by Field Emission Scanning Electron Microscopy (FE-SEM), Fourier Transform Infra-Red Spectroscopy (FT-IR) and X-ray Diffraction (XRD). Electrochemical characterizations were also measured by cyclic voltammetry and galvanostatic charge-discharge tests. |
