Abstract

Single-atom catalysts (SACs) hold great promise for powering fast and durable sulfur electrochemistry in lithium-sulfur batteries (LSBs). The rational manipulation of SAC local structure is a key strategy for boosting catalytic activity and enhancing battery performance, spurring significant research interest in recent years. This comprehensive review combs through the latest progress of SACs in LSBs, with a particular emphasis on the modulations of their local structure and catalytic behaviors. These advancements are classified into three main categories, i.e., center-substrate matchup, coordination adjustment, and composite synergism, according to the primary design principle and the polysulfide catalytic conversion mechanism. Furthermore, we critically and systematically investigate the remaining challenges in LSBs and suggest strategic solutions in the design, synthesis, and application of SACs. By providing a systematic summary and profound insights into the local structure modulation, this review offers guidance for the development of advanced SACs and practically viable LSBs.

硫电催化中单原子催化剂的局部结构调制：综述

单原子催化剂（SACs）在锂硫电池（LSBs）中为快速、持久的硫电化学提供动力方面前景广阔。合理操纵SAC局部结构是提高催化活性和提高电池性能的关键策略，近年来引起了广泛的研究兴趣。本文综述了LSBs中SACs的最新研究进展，重点介绍了其局部结构和催化行为的调控。根据主要设计原理和多硫催化转化机理，将这些进展分为中心-底物匹配、配位调节和复合协同作用三大类。此外，我们批判性地、系统地研究了LSBs中存在的挑战，并提出了sac设计、合成和应用方面的战略解决方案。本文通过对局部结构调制的系统总结和深刻见解，为先进的sac和实际可行的lsdb的发展提供指导。
