“…In previous reports, iron-based compounds have a strong adsorption effect on polysulfides, especially the excellent anchoring effect of Fe 7 S 8 nanoparticles on polysulfides. [109][110][111] Meanwhile, cobalt-based compounds can provide a large number of catalytic active sites, accelerating the conversion of polysulfides. [112][113][114] Combining the advantages of the two to design a heterostructure can further improve the utilization rate of sulfur.…”

The commercialization of Li−S batteries is seriously hindered by polysulfides with severe shuttle effect, and the inherent insulating properties and slow reaction kinetics of insoluble Li2S products. Transition metal sulfides (TMSs) have a high adsorption capacity for polysulfides and have been shown to have a strong catalytic effect on polysulfide conversion reactions. This paper reviews the research on the application of Unary TMSs, heterostructures, etc. in Li−S batteries, and gives some research methods for TMD catalysts in Li−S batteries. Finally, it points out the main focuses and direction of future Li−S battery research and development. It aims to provide some insights into the design and manufacture of advanced Li−S batteries for commercial use.

of lithium-ion batteries on a large scale. Therefore, the development of rechargeable batteries with high energy density and reliability would be a priority. One of the most promising candidates is lithiumsulfur (Li-S) batteries, which have great potential for addressing these issues. [5][6][7] The conversion reaction based on the reduction of sulfur to lithium sulfides (Li 2 S) yields a high theoretical capacity of 1675 mAh g −1 (S 8 + 16 Li = 8 Li 2 S). Such a capacity is significantly higher than that of insertion cathode materials such as LiCoO 2 and LiFePO 4 , which deliver capacities below 200 mAh g −1 . The 16-electron electrochemical charge transfer reaction with a working voltage of about 2.2 V allows a specific energy density of 2600 Wh kg −1 for Li-S batteries. With optimal configuration, a practical energy density of 500-600 Wh kg −1 would be achievable when considering additional battery components. [8] Moreover, sulfur possesses the merits of abundant resources, safety, and environmental friendliness. The breakthrough in Li-S batteries will promote the development and application of renewable energy.Despite the great potential for replacing lithium-ion batteries, Li-S batteries still face several critical problems. [9] The principal one is the sluggish conversion kinetics of the sulfur reduction reaction (SRR) during discharging due to the low conductivity of sulfur species and complicated 16-electron conversion Lithium-sulfur batteries are one of the most promising alternatives for advanced battery systems due to the merits of extraordinary theoretical specific energy density, abundant resources, environmental friendliness, and high safety. However, the sluggish sulfur reduction reaction (SRR) kinetics results in poor sulfur utilization, which seriously hampers the electrochemical performance of Li-S batteries. It is critical to reveal the underlying reaction mechanisms and accelerate the SRR kinetics. Herein, the critical issues of SRR in Li-S batteries are reviewed. The conversion mechanisms and reaction pathways of sulfur reduction are initially introduced to give an overview of the SRR. Subsequently, recent advances in catalyst materials that can accelerate the SRR kinetics are summarized in detail, including carbon, metal compounds, metals, and single atoms. Besides, various characterization approaches for SRR are discussed, which can be divided into three categories: electrochemical measurements, spectroscopic techniques, and theoretical calculations. Finally, the conclusion and outlook part gives a summary and proposes several key points for future investigations on the mechanisms of the SRR and catalyst activities. This review can provide cutting-edge insights into the SRR in Li-S batteries.
