Lithium–sulfur batteries (LSBs) are considered candidates for next-generation energy storage systems due to their high theoretical density and low cost. However, practical applications constrained by the shuttle effect, lithium dendrites, conductivity, volume expansion of sulfur. Metal–organic frameworks (MOFs) have emerged as promising materials addressing these challenges, owing exceptional adsorption catalysis capabilities, coupled with a readily adjustable form-factor design. This review provides broader perspective comprehensively examining MOFs in LSBs, covering roles cathodes, separators, electrolytes from multiple dimensions, including reaction mechanisms, development potential cathode materials, positive impacts on LSBs’ performance achieved through preparation modifications intermediate, separator, electrolyte. Finally, we provide perspectives future directions this field.

The development of functional interlayers to effectively anchor lithium polysulfide and enhance the integrity sulfur cathodes in lithium-sulfur (Li-S) batteries has received significant global consideration. However, identifying an interlayer that is both highly conductive structurally robust remains a major challenge. This study presents synthesis three-dimensional nitrogen-doped carbon microspheres embedded with bismuth selenide nanocrystals (referred as “three-dimensional (3D) Bi2Se3@N-C” microspheres) evaluates their role barrier for enhanced Li-S battery performance. Bi2Se3 within provide numerous active spots chemical captivity electrocatalytic transformation species. Moreover, N-doped framework facilitates speedy transfer charge moieties, resulting faster redox activity. Correspondingly, cells paired 3D Bi2Se3@N-C microsphere modified separators exhibit excellent rate capability (297 mA h g-1 at 2.0 C-rate) prolonged stable cycling performance different C-rates (863 after 100 cycles 0.1 C, 440 200 0.5 219 500 C). cell demonstrates satisfactory retaining 57% its capacity when material loading was raised 3.5 mg cm-2, confirming practical feasibility prepared nanostructure. detailed physical electrochemical results presented this offer valuable perceptions expansion superior, conductive, easily scalable nanostructures various energy storage demands.

Lithium–sulfur batteries have become glamorous candidates benefitting from their attractive specific capacity (1675 mAh g–1) and nontoxic properties, but the existing problems remain to be solved. In this work, CoSe2–nitrogen-doped carbon (CSN) connected by nanotubes was synthesized with Prussian blue melamine as a precursor source, respectively, named CSNC, which has high electronic conductivity anchoring effect on lithium polysulfides (LiPSs). CSNC is used both sulfur carrier separator modification material. Furthermore, stable framework slows down volume change during operation of batteries. Electrochemical impedance spectroscopy Randles–Sevcik equation calculation verify that promotes transformation reaction kinetics LiPSs, UV–vis absorption spectrum confirms effective adsorption for accordingly inhibiting shuttle effect. Because above advantages, lithium–sulfur battery CSNC/S + CSNC/PP achieves discharge 1056 g–1 at 0.5 C retention 85.5% over 100 cycles.
