Lithium-sulfur (Li-S) batteries are promising energy storage devices owing to their high theoretical specific capacity and energy density. However, several challenges, including volume expansion, slow reaction kinetics, polysulfide shuttle effect and lithium dendrite formation, hinder their commercialization. Separators are a key component of Li-S batteries. Traditional separators, made of polypropylene and polyethylene, have certain limitations that should be addressed. Therefore, this review discusses the basic properties and mechanisms of Li-S battery separators, focuses on preparing different functionalized separators to mitigate the shuttle effect of polysulfides. This review also introduces future research trends, emphasizing the potential of separator functionalization in advancing the Li-S battery technology.
锂硫（Li-S）电池因其高理论比容量和能量密度而成为很有前景的储能装置。然而，包括体积膨胀、反应动力学缓慢、多硫化物穿梭效应和锂枝晶形成在内的几个挑战阻碍了它们的商业化。隔膜是锂硫电池的关键组件。由聚丙烯和聚乙烯制成的传统隔膜存在一些需要解决的局限性。因此，本综述讨论了锂硫电池隔膜的基本性质和机理，重点在于制备不同的功能化隔膜以减轻多硫化物的穿梭效应。本综述还介绍了未来的研究趋势，强调了隔膜功能化在推动锂硫电池技术发展方面的潜力。
