“…Despite the attractive sulfur loading, a major drawback of these sulfur copolymers is their low electrical conductivity, which warrants the need for conductive fillers and hosts 83,87 . In the above examples, the sulfur copolymers were either physically mixed with the carbon filler or melt‐infiltrated into the carbon host.…”

Room-temperature sodium-sulfur batteries (NaSBs) are promising candidates for next-generation large-scale energy storage solutions. However, the wellknown polysulfide shuttling of soluble long-chain sulfur intermediates still remains a limitation in NaSBs, leading to rapid capacity loss arising from the dissolution of active sulfur into the electrolyte. This problem is effectively circumvented in quasi-solid-state conversion cathodes by elimination of the presence of these soluble intermediates altogether, with only insoluble intermediates formed in the process. Herein, we discuss various cathode materials that undergo quasi-solid-state conversion when cycled in a liquid electrolyte, including chemically bonded short-chain sulfur species, shortchain sulfur via physical confinement, and quasi-solid-state conversion cathodes with long-chain sulfur moieties. We conclude by highlighting the current challenges and possible strategies to improve the mechanistic understanding and cycling performance of NaSBs for practical applications.

“…Along with popularization of portable electronics and new energy vehicles, high energy density batteries have recently aroused enormous research interest. As one of the most promising new-generation battery technologies, lithium–sulfur (Li–S) rechargeable batteries have gained much attention because of their ultrahigh theoretical energy density (2600 Wh kg –1 ), environmental friendliness, and low cost of the sulfur cathode. − Howbeit, various issues including the low conductivity of active sulfur (10 –30 S cm –1 ) and the final discharge product lithium sulfide (10 –14 S cm –1 ), the enormous volumetric variation of the sulfur cathode upon cycling, and the shuttle effect still impede their industrial application. − In particular, the shuttle effect caused by severe dissolution and fast diffusion of polysulfide (Li 2 S n , n = 4, 6, and 8) intermediates upon discharge–charge cycles leads to low reversible capacity, low energy efficiency, and fast capacity decay. − …”

Lithium–sulfur (Li–S) batteries hold great promise for new-generation energy storage technologies owing to their overwhelming energy density. However, the poor conductivity of active sulfur and the shuttle effect limit their widespread use. Herein, a carbon cloth decorated with thiol-containing UiO-66 nanoparticles (CC@UiO-66(SH)2) was developed to substitute the traditional interlayer and current collector for Li–S batteries. One side of CC@UiO-66(SH)2 acts as a current collector to load active materials, while the other side serves as an interlayer to further restrain polysulfide shuttling. This two-in-one integrated architecture endows the sulfur cathode with fast electron/ion transport and efficient chemical confinement of polysulfides. More importantly, rich thiol groups in the pores of UiO-66(SH)2 serve to tether polysulfides by both covalent interactions and lithium bonding. Therefore, the Li–S battery equipped with this integrated interlayer–current collector not only delivers an enhanced specific capability (1209 mAh g–1 at 0.1 C) but also exhibits prominent cycling stability (an attenuation rate of 0.037% per cycle for 1000 cycles at 1 C). Meanwhile, the battery achieves a high discharge capacity of 795 mAh g–1 at a sulfur loading of 3.83 mg cm–2. The new metal–organic framework (MOF)-based electrode material reported in this study undoubtedly provides insights into the exploration of functional MOFs for robust Li–S batteries.
