Rechargeable lithium-sulfur (Li–S) batteries are considered as promising candidates for next-generation energy storage devices due to their high capacity and high energy density. However, their large-scale practical applications suffer from a series of challenges, such as the insulating nature of sulfur, the shuttle effect of soluble lithium polysulfides (LiPSs), and the volume expansion upon lithiation. Numerous research work proved that modification of the cathodes with host materials is efficient for alleviating these issues. Two-dimensional (2D) materials have recently emerged as a candidate of choice for the sulfur host materials. Herein, a comprehensive review of the recent advances in 2D sulfur host materials is presented, including the mechanism of Li–S batteries and the basic requirement for hosts. Furthermore, different types of 2D hosts are summarized and discussed in detail. Finally, an outlook of possible research directions, challenges, and perspectives are presented. This review paves the way for the rational design of 2D host materials for Li-S battery applications.

可充电锂硫（Li-S）电池因其高容量和高能量密度而被认为是下一代储能设备的有希望的候选者。然而，它们的大规模实际应用面临一系列挑战，例如硫的绝缘性、可溶性多硫化锂（LiPSs）的穿梭效应以及锂化后的体积膨胀。大量研究工作证明，用主体材料对正极进行改性可以有效缓解这些问题。二维 (2D) 材料最近已成为硫主体材料的候选材料。本文全面回顾了二维硫主体材料的最新进展，包括锂硫电池的机理和对主体的基本要求。此外，对不同类型的 2D 主机进行了总结和详细讨论。最后，对可能的研究方向、挑战和前景进行了展望。本综述为锂硫电池应用的二维主体材料的合理设计铺平了道路。
