Wide application of metal-organic frameworks in lithium–sulfur battery

Lithium–sulfur battery (LSB), as a secondary battery with high energy density, is considered as a promising material for energy storage. However, problems such as shuttle effect, lithium dendrites, low conductivity of sulfur, and volume expansion of sulfur make it difficult for LSBs to be used commercially. Previous studies have shown that metal-organic framework (MOF) materials have a wide range of applications in improving the performance of LSBs due to their excellent adsorption and catalytic capacity and designable structure. In this paper, the latest applications of MOF materials, MOF-derived materials, and MOF composites in LSBs are reviewed. It covers separator, electrolyte, cathode, anode, and other fields. The reaction mechanism of MOF materials in LSBs and the design ideas of researchers were summarized and more applications of MOF materials in the direction of LSBs were prospected. This paper starts with the principles and research methods of LSBs and provides guidance for the application of MOF materials in LSBs.
