Review highlights progress on 3d 10 -based catalysts for polysulfide reduction in lithium-sulfur batteries, suggesting improvements on redox kinetics and shuttle effect mitigation.
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 10 ‐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 10 ‐based catalysts to improve the polysulfide reduction reaction are summarized. Finally, we summarize the challenges faced by 3d 10 ‐based materials in LSBs applications and present an outlook to improve the reference for the design of next‐generation LSBs materials.
