Lithium-sulfur batteries (LSBs), with their high energy density compared to lithium-ion batteries, are now strong candidates for next-generation energy storage systems. However, insufficient redox kinetics leads to shuttle effect and lithium dendrites, which hinder their commercial application. In this paper, the latest progress of 3d-based materials such as copper, zinc and their composites as cathode materials for LSBs is discussed, and the kinetics of polysulfide reduction catalyzed by copper-zinc-based materials and the mechanism of restraining shuttle effect are discussed in detail. Several strategies for the rational design of 3d-based catalysts to improve the polysulfide reduction reaction are summarized. Finally, we summarize the challenges faced by 3d-based materials in LSBs applications and present an outlook to improve the reference for the design of next-generation LSBs materials.
锂硫电池（LSB）与锂离子电池相比具有高能量密度，目前是下一代储能系统的有力候选者。然而，氧化还原动力学不足会导致穿梭效应和锂枝晶，这阻碍了它们的商业应用。本文讨论了铜、锌及其复合材料等三维基材料作为锂硫电池阴极材料的最新进展，并详细讨论了铜锌基材料催化多硫化物还原的动力学以及抑制穿梭效应的机制。总结了合理设计三维基催化剂以改善多硫化物还原反应的几种策略。最后，我们总结了三维基材料在锂硫电池应用中面临的挑战，并展望未来以改进下一代锂硫电池材料设计的参考依据。
