Lithium-sulfur (Li-S) batteries are a highly promising next-generation high-energy battery due to their advantages such as high energy density (2600 Wh kg–1), abundant crustal reserves, low cost, and low toxicity. However, the insulating nature of the sulfur cathode and the dissolution of lithium polysulfides (LiPSs) in the electrolyte during the reaction process lead to irreversible capacity loss, known as the shuttle effect, which severely hinders the practical application of Li-S batteries. Therefore, designing functionalized separators to effectively suppress LiPSs shuttling, promote electron/ion transport, accelerate sulfur conversion, and ultimately improve sulfur utilization and cycling stability is particularly important.
