“…[8,33,39,40] Introducing catalytic hosts to accelerate the redox conversion of polysulfides has been shown to be a fundamental solution to resolve these issues. [9,[41][42][43][44][45] To date, a variety of electrocatalysts, including heteroatom-doped/defect-rich carbon materials, [26,38,17] metal sulfides, [46][47][48][49][50] metal oxides, [7,[51][52][53][54][55] metal nitrides, [56][57][58][59][60][61][62] metal phosphides [63][64][65][66][67] , and heterostructures, [6,[68][69][70][71] have been developed and utilized as sulfur hosts. In particular, numerous comprehensive reviews have summarized the progress of electrocatalysts from the viewpoint of microstructure and electronic structure regulation.…”

The current research of Li–S batteries primarily focuses on increasing the catalytic activity of electrocatalysts to inhibit the polysulfide shuttling and enhance the redox kinetics. However, the stability of electrocatalysts is largely neglected, given the premise that they are stable over extended cycles. Notably, the reconstruction of electrocatalysts during the electrochemical reaction process has recently been proposed. Such in situ reconstruction process inevitably leads to varied electrocatalytic behaviors, such as catalytic sites, selectivity, activity, and amounts of catalytic sites. Therefore, a crucial prerequisite for the design of highly effective electrocatalysts for Li–S batteries is an in‐depth understanding of the variation of active sites and the influence factors for the in situ reconstruction behaviors, which has not achieved a fundamental understanding and summary. This review comprehensively summarizes the recent advances in understanding the reconstruction behaviors of different electrocatalysts for Li–S batteries during the electrochemical reaction process, mainly including metal nitrides, metal oxides, metal selenides, metal fluorides, metals/alloys, and metal sulfides. Moreover, the unexplored issues and major challenges of understanding the reconstruction chemistry are summarized and prospected. Based on this review, new perspectives are offered into the reconstruction and true active sites of electrocatalysts for Li–S batteries.

“…Sulfur electrodes can be conjugated with a range of metal anodes in rechargeable metal-sulfur (M-S) batteries and have demonstrated promising potential for practical energy-storage applications. [1][2][3][4][5][6][7] However, sulfur reduction reaction (SRR) and sulfur oxidation reaction (SOR) in M-S batteries involve conversions between various solid-state insulating elemental sulfur, metal disulfides and metal sulfides. [8,9] The high kinetical bottleneck of these solid-state sulfide conversions causes large overpotentials and incomplete conversion even under low rates, leading to low discharged capacity and fast capacity decay.…”

Improving kinetics of solid-state sulfide conversion in sulfur cathodes can enhance sulfur utilization of metal-sulfur batteries. However, fundamental understanding of the solid-state conversion remains to be achieved. Here, taking potassium-sulfur batteries as a model system, we for the first time report the reducing overpotential of solid-state sulfide conversion via the meta-stable S 3 2À intermediates on transition metal single-atom sulfur hosts. The catalytic sulfur host containing Cu single atoms demonstrates high capacities of 1595 and 1226 mAh g À 1 at current densities of 335 and 1675 mA g À 1 , respectively, with stable Coulombic efficiency of � 100 %. Combined spectroscopic characterizations and theoretical computations reveal that the relatively weak Cu-S bonding results in low overpotential of solid-state sulfide conversion and high sulfur utilization. The elucidation of solid-state sulfide conversion mechanism can direct the exploration of highly efficient metal-sulfur batteries.

“…1,2 Lithium-sulfur batteries are examples of rechargeable electrochemical batteries and have garnered considerable attention due to their excellent electrochemical performance and energy density. [3][4][5][6][7][8] However, the organic electrolyte that these batteries use is expensive, toxic, and flammable, which can lead to serious safety issues in some environments. Thus, the replacement of organic electrolyte with aqueous electrolyte in rechargeable batteries is necessary.…”
