Abstract

Lithium-sulfur batteries (LSBs) have undoubtedly become one of the most promising battery systems due to their high energy density and the cost-effectiveness of sulfur cathodes. However, challenges, such as the shuttle effect from soluble long-chain lithium polysulfides (LiPSs) and the low conductivity of active materials, hinder their commercialization. Under this circumstance, molybdenum sulfide (MoS₂) has attracted widespread attention due to its unique physicochemical properties, particularly its capability to mitigate the shuttle effect in LSBs through electrostatic or chemical bonds. Nonetheless, the industrial application of MoS₂ in LSBs is limited by the inertness of its basal surface and inadequate electron transfer properties. This review mainly introduces various modification strategies of MoS₂ materials in LSBs and their effects on electrochemical and catalytic performance. Unlike previous reviews and related papers, detailed discussions were conducted on the specific mechanisms of each modification strategy, including (1) shape manipulation, (2) support engineering, (3) heterostructure engineering, (4) defect engineering, (5) interlayer engineering, (6) phase engineering, (7) strain engineering, (8) hybridization. Comprehensive conclusions and outlook on the development of MoS₂ as an abundant electrocatalyst for LSBs are also discussed in the end.

面向实用高性能锂硫电池的硫化钼改性策略综述

锂硫电池（LSBs）由于其高能量密度和硫阴极的成本效益，无疑已成为最有前途的电池系统之一。然而，诸如可溶性长链多硫化锂（LiPSs）的穿梭效应和活性材料的低电导率等挑战阻碍了它们的商业化。在这种情况下，硫化钼（MoS2）由于其独特的物理化学性质，特别是通过静电或化学键来减轻lsb中的穿梭效应而引起了广泛的关注。然而，MoS2在lsdb中的工业应用受到其基面惰性和不充分的电子转移特性的限制。本文主要介绍了MoS2材料在lbs中的各种改性策略及其对电化学和催化性能的影响。与以往的综述和相关论文不同，本文对每种改性策略的具体机制进行了详细的讨论，包括(1)形状操纵，(2)支撑工程，(3)异质结构工程，(4)缺陷工程，(5)层间工程，(6)相工程，(7)应变工程，(8)杂交。最后对MoS2作为一种丰富的lsdb电催化剂的发展前景进行了展望。图形抽象
