With the development of the EV industry, there comes a thrive and high demand in the Lithium-Ion battery. Also, there are great demand for the new generation of battery. Due to the growing need to reduce battery charging times, the ability to handle high current rates (C-rates) is becoming increasingly important in real-world applications. Lithium-sulfur batteries, with their higher theoretical capacity, are viewed as promising options for future battery technology.In this work, A tailored mesoporous Co-MOF(ZIF-67) as the sulfur host for the cathode side of the lithium sulfur battery is reported. The study motivated from the fact single cobalt site can be sulfurize into cobalt sulfide site with the property of adsorption and the catalysis of polysulfides. The study dives into tailoring the property of ZIF-67 into mesoporous and conductive by changing the solvent and growing ZIF-67 crystals with Graphene. The substrate was characterized by a comprehensive array of techniques including Scanning electron microscopy (SEM), Energy-dispersive X-ray spectroscopy (EDS), Brunauer-Emmett-Teller surface area analysis (BET), X-Ray diffraction analysis (XRD), Fourier Transform Infrared Spectroscopy (FT IR). It’s sulfur hosting and polysulfide adsorption capability has been tested by Thermogravimetric Analysis (TGA), Ultraviolet–visible spectroscopy (UV-vis). Its electrochemical performance and cell performance has also been fully investigated. The study concludes with recommendations for future directions including voiding high temperature treatment introducing MOF into cell by directly synthesize the mesoporous and conductive structure with active metal site.
