Abstract

Abstract: Lithium–sulfur batteries are recognized as one of the most promising next‐generation energy‐storage technologies owing to their high energy density and low cost. Nevertheless, the shuttle effect of polysulfide intermediates and the formation of lithium dendrites are the principal reasons that restrict the practical adoption of current Li–S batteries. Adjustable frameworks, structural variety, and functional adaptability of covalent organic frameworks (COFs) have the potential to overcome the issues associated with Li–S battery technology. Herein, a summary is presented of emerging COF materials in addressing the challenging problems in terms of sulfur hosts, modified separators, artificial solid electrolyte interphase layers, and solid‐state electrolytes. This comprehensive overview focuses on the design and chemistry of COFs used to upgrade Li–S batteries. Furthermore, existing difficulties, prospective remedies, and prospective research directions for COFs for Li–S batteries are discussed, laying the groundwork for future advancements in this class of fascinating materials. Abstract : Covalent organic frameworks with tunable pore structures, structural diversity, and functional versatility are essential for boosting high‐energy rechargeable lithium‐sulfur batteries. This review presents the opportunities and challenges of directly using covalent organic frameworks as host materials, modified layers, artificial solid electrolyte interphase layers, and solid‐state electrolytes in lithium–sulfur batteries. Finally, the remaining challenges and prospects are thoroughly discussed.
