“…Constructing flexible and highly conductive MOF composites is capable of overcoming these hurdles. There have been many studies that introduce CNTs, [352][353][354] rGO, [355] polymers, [356] and other carbon materials [357] to MOFs to produce composite materials. For instance, Mao et al designed a foldable interpenetrated MOF/CNT thin film as binder-free and flexible host.…”

Metal-organic frameworks (MOFs) are a class of porous materials with unprecedented chemical and structural tunability. Their synthetic versatility, long-range order, and rich host-guest chemistry make MOFs ideal platforms for identifying design features for advanced functional materials. This review addresses synthetic approaches to control MOF attributes for realizing material properties such as charge conductivity, stability, surface area, and flexibility. Along with an updated account on MOFs employed in batteries and supercapacitors, new directions are outlined for advancing MOF research in emergent technologies such as solid-state electrolytes and battery operation in extreme environments. G lobal demands for clean energy storage and delivery continue to push developing technology to its limits. Batteries and supercapacitors are among the most promising technologies for electrical energy storage owing to their portability and compact size for on-demand usage. Despite their promise, chemical and physical limitations of existing materials hinder performance and require new, creative solutions. For instance, polymers and conductive carbon materials are relatively inexpensive, scalable, and synthetically tunable but can lack physical and chemical stability for device implementation. On the other hand, solid inorganic materials, such as metal oxides and silicon, are used as electrode materials due to their robust structure and redox-active sites. However, sluggish ion diffusion of metal oxides limit charge/ discharge rate capabilities and large volumetric changes lead to mechanical instability. Drawbacks in these current platforms motivate the discovery and development of new materials for advanced energy storage devices. Metal-organic frameworks (MOFs) are attractive candidates to meet the needs of nextgeneration energy storage technologies. MOFs are a class of porous materials composed of metal nodes and organic linkers. Their modular nature allows for great synthetic tunability, affording both fine chemical and structural control. With creative synthetic design, properties such as porosity, stability, particle morphology, and conductivity can be tailored for specific applications. As the needs of each energy storage device are different, this synthetic versatility of MOFs provides a method to optimize materials properties to combat inherent electrochemical

“…After being physically/chemically absorbed, polysulfides will be further reduced to insoluble sulfides and fixed in the trapping layer. On the basis of the physical/chemical adsorption effect, some trapping materials also exhibit good catalytic activity for the polysulfide reduction reaction . Metal sulfides like Co 9 S 8 , MoS 2 , VS 4, and WS 2 were used in lithium‐sulfur batteries as catalytic trapping materials.…”

“…Wang et al applied VS 4 nanorod anchored 3‐D graphene to modify the separator, which could adsorb polysulfides and accelerate polysulfide redox kinetics, enabling the battery to exhibit excellent cyclability and rate performance. Besides metal sulfides, metal oxides including In 2 O 3 , MoO x , MnO 2 , and HfO 2 also have high catalytic activity for the polysulfide reduction reaction. Song et al prepared a MnO 2 ‐coated PE separator in which the MnO 2 not only adsorbed polysulfides but also promoted the formation of an insoluble mediator through the catalytic effect.…”

The lithium-sulfur battery is considered one of the most promising candidates for portable energy storage devices due to its low cost and high energy density.However, many critical issues, including polysulfide shuttling, self-discharge, lithium dendritic growth, and thermal hazards need to be addressed before the commercialization of lithium-sulfur batteries. To this end, tremendous efforts have been made to explore battery configurations and components, such as electrodes, electrolytes, and separators, among which the separator plays an especially critical role in addressing aforementioned issues. Thus, this review analyzes the mechanisms and interactions of these critical issues and summarizes both the function of separators and recent progress made towards remedying such issues. Additionally, promising directions for the development of separators in lithium-sulfur batteries are proposed. K E Y W O R D Slithium dendrite, lithium-sulfur batteries, self-discharge, separator, shuttle effect, thermal hazardsThe first two authors contributed equally to this work.
