Metal-sulfur batteries have become potential candidates for the next generation of energy storage systems due to their high theoretical energy density and environmental friendliness. However, they face many challenges in practical applications, such as the low conductivity of sulfur and capacity degradation caused by the polysulfide shuttle effect. Metal-organic frameworks (MOFs) and Covalent-organic frameworks (COFs) have shown great potential in solving these problems due to their unique structural and chemical properties. This article reviews the applications of MOFs and COFs as positive electrode materials and separator coatings in metal sulfur batteries. Firstly, the working principle and primary challenges faced by metal sulfur batteries have been introduced, followed by the basic properties of MOFs and COFs. Then, the applications of MOFs/COFs in metal sulfur batteries have been discussed, focusing on their role in improving sulfur conductivity, suppressing polysulfide shuttle effects, and enhancing separator selectivity and stability. In the design and performance optimization of positive electrodes, the effects of different synthesis methods on the structure and properties of MOFs/COFs were analyzed, and methods for optimizing material properties through pore size, surface functionalization, and conductivity enhancement were explored. In the section on separator coating, preparation methods such as coating, impregnation, and electrospinning have been discussed.
