Rechargeable metal-sulfur batteries are considered promising candidates for energy storage due to their high density along with natural abundance and low cost of raw materials. However, they could not yet be practically implemented several key challenges: (i) poor conductivity sulfur the discharge product metal sulfide, causing sluggish redox kinetics, (ii) polysulfide shuttling, (iii) parasitic side reactions between electrolyte anode. To overcome these obstacles, numerous strategies have been explored, including modifications cathode, anode, electrolyte, binder. In this review, fundamental principles challenges first discussed. Second, latest research on is presented discussed, covering material design, synthesis methods, electrochemical performances. Third, emerging advanced characterization techniques that reveal working mechanisms highlighted. Finally, possible future directions practical applications This comprehensive review aims provide experimental theoretical guidance designing understanding intricacies batteries; thus, it can illuminate pathways progressing high-energy-density battery systems.

Currently, lithium sulfur (Li-S) battery with high theoretical energy density has attracted great research interest. However, the diffusion and loss process of intermediate polysulfide during charge-discharge hindered application Li-S in modern life. To overcome this issue, metal organic frameworks (MOFs) their composites have been regarded as effective additions to restrain LiPS for battery. Benefiting from unique structure rich active sites adsorb accelerate redox, batteries MOFs modified exhibit superior electrochemical performance. Considering rapid development battery, review summarizes recent studies host materials, functional interlayer, separator coating layer, separator/solid electrolyte detail. In addition, promising design strategies MOF materials are proposed improve performance

Lithium-sulfur batteries (LSBs) are regarded as promising next-generation energy-storage devices due to high energy density, low cost, and environmental friendliness. However, their commercial viability is hindered by the shuttle effect of lithium polysulfides (LiPSs) slow redox kinetics. Transition metal chalcogenide derivatives (TMCs, including sulfides, selenides, tellurides) from metal-organic frameworks (MOFs) emerging nanomaterials that have garnered significant attention because porosities, superior electron conductivities, excellent electrocatalytic activities, lithiophilicities. The potential MOFs templates obtain TMCs for LSBs increasingly being explored. This review highlights latest developments MOF-derived catalytic materials LSBs, focusing on synthesis these materials, modifications electrodes separators, reaction mechanism LiPSs in presence catalysts achieve Coulombic efficiency long cycle life. Finally, challenges prospects discussed.

ABSTRACT The microstructure and electrochemical corrosion performance of vacuum cladding FeNiCoCrMoBSi HEA coatings were investigated. results show that the coating forms an FCC+σ eutectic structure. FCC matrix phase has abalone crystal diffraction angle plane (111) is positively correlated with remelting temperature, while its peak intensity grain size are inversely correlated. Unlike obtained at temperatures 1150°C 1230°C, where σ a Mo poor phase, temperature 1190°C Mo‐rich phase. lowest self‐corrosion current density (3.31 μA/cm 2 ), highest potential (−0.3797 V), polarization impedance (69 616 Ω), modulus (23 205.68 W cm ). Its 2.89 times 2.04 higher than those remelted respectively, demonstrating excellent resistance. This can be attributed to comprehensive effect various factors, such as dual phases, dense structure, passivation film.
