“…Hollow-structure-based materials stick out for abundant void spaces to accommodate sulfur species and increase the density of catalytic sites. [228] In the initial stage, a variety of carbonbased hollow structures derived from hard or soft templates provided enormous opportunities for enhancing the sulfur loading amount in cathodes. [47,[229][230][231] A hollow carbon sphere (HCS) prepared by the sacrificial template method was first used as the sulfur host, and a high sulfur loading of 70 wt% could be achieved when exposed to sulfur vapor three times.…”

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.

“…It is undeniable that the application of Li‐S and Na‐S batteries plays tremendous roles in energy storage devices and wearable devices nowadays 39‐43 . Despite the merits of high specific capacity, low cost, high electrode efficiency and almost nontoxicity, we are still plagued by its poor rate performance, short cycle life and low coulomb efficiency 44‐47 . For instance, (a) During electrode charging and discharging, intermediates such as insulating S, Li, and soluble Li polysulfide will be produced, which induce a “shuttle effect” 48 .…”

Improved MXenes based on heteroatom doping endow them with various new or optimized physicochemical, optical and structural properties. This greatly expands the library of MXenes materials and their potential for a range of applications. In this article, we comprehensively and critically discuss the synthesis and performance of the growing heteroatom doping and its family of composite MXenes materials in metal-sulfur batteries. We first summarize the heteroatom doping and its composite strategy of high-performance MXenes and analyze and summarize the mechanism of atomic element doping from three aspects: structure optimization, functional substitution and interface modification, aiming to provide clues for the development of new controllable synthetic routes. Emerging synthesis and optimization mechanisms related to metal-sulfur batteries are highlighted. Finally, we propose future opportunities and challenges for multifunctional high-performance MXenes research and metal-sulfur batteries. This work could open up new prospects for the development of high-performance MXenes in metal-sulfur batteries.

“…5 To solve the above problems, various conducting support materials, particularly with hollow micro/nanostructures, 6 have been adopted to load sulfur species with reduced polarization and increased utilization of sulfur cathodes. Particularly, various carbon substrates, such as ordered mesoporous carbon, 7 (porous) carbon (nano)spheres, [8][9][10][11][12][13] carbon nanotubes, [14][15][16] graphene, 17 etc., with controllable pore structures and morphologies, have been studied as sulfur hosts due to their high electrical conductivity, light weight and low cost.…”
