“…The peaks at 162.9 and 161.4 eV conform to S 2p 1/2 and S 2p 3/2 , indicating the existence of S 2− in CIS/GO@3D-OMA-3. 35 Moreover, three peaks at 168.4, 166.0, and 164.8 eV correspond to SO 4 2− , SO 3 2− , and S–O, 36 respectively, which may be due to the combination of the CIS with GO or ALG. The C 1s spectra of CIS/GO@3D-OMA-3 and GO are shown in Fig.…”

Metal–sulfur batteries constitute an extraordinary research playground that ranges from fundamental science to applied technologies. However, besides the widely explored Li-S system, a remarkable lack of understanding hinders advancements and performance in all other metal–sulfur systems. In fact, similarities and differences make all generalizations highly inconsistent, thus unavoidably suggesting the need for extensive research explorations for each formulation. Here we review critically the most remarkable open challenges that still hinder the full development of metal-S battery formulations, starting from the lithium benchmark and addressing Na, K, Mg, and Ca metal systems. Our aim is to draw an updated picture of the recent efforts in the field and to shed light on the most promising innovation paths that can pave the way to breakthroughs in the fundamental comprehension of these systems or in battery performance.

“…[98] Owning to their high electrical conductivity and good structural tailor-ability, the carbon-based scaffold has been recognized as an optimal candidate for engineering vacancy-based catalytic materials. [126,127] Previous work has demonstrated that the edge sites of carbon vacancy present higher oxygen reduction reaction activity. [128] The introduction of intrinsic vacancy into carbon to expose more marginal sites is expected to increase the reaction kinetics of polysulfide redox catalysis, which has already been widely reported for the oxygen reduction reaction.…”

Advanced metal-sulfur batteries (MSBs) are regarded as promising next-generation energy storage devices. Recently, engineering polysulfide redox catalysts (PSRCs) to stabilize and catalytically convert polysulfide intermediates is proposed as an effective strategy to address the grand challenge of "shuttle effects" in the cathode. Therefore, modulating the bond interactions and interface microenvironments and disclosing the structure-performance correlations between polysulfide and catalysts are essential to guide the future cathode design in MSBs. Herein, from a multidisciplinary view, the most recent process in the reaction principles, in situ characterizations, bond interaction modulation, and interface microenvironment optimization of polysulfide redox catalysts, is comprehensively summarized. Especially, unique insights are provided into the strategies for tailoring the bond interactions of PSRCs, such as heteroatom doping, vacancy engineering, heterostructure, coordination structure arrangements, and crystal phase modulation. Furthermore, the importance of interface microenvironments and substrate effects in different PSRCs are exposed, and a detailed comparison is given to unveil the critical parameters for their future developments. Finally, the critical design principles on electrode microenvironments for advanced MSBs are also proposed to stimulate the practically widespread utilization of PSRCs-equipped cathodes in MSBs. Overall, this review provides cutting-edge guidance for future developments in high-energy-density and long-life MSBs.
