“…Pristine MOFs and hybrid MOFs have been also extensively studied as separators [82,93,310,[419][420][421][422] or coating layers integrated separators [94,95,311,[423][424][425][426][427][428][429][430][431][432][433][434][435][436] in LSBs. For instance, a Cu MOF (HKUST-1) constructed by H 3 BTC, L8, and Cu(NO 3 ) 2 •3H 2 O was well connected by binder PVDF-HFP as separators in LSBs to show blocking polysulfides diffusion (Figure 16a,b).…”

The preparation of electroactive metal–organic frameworks (MOFs) for applications of supercapacitors and batteries has received much attention and remarkable progress during the past few years. MOF‐based materials including pristine MOFs, hybrid MOFs or MOF composites, and MOF derivatives are well designed by a combination of organic linkers (e.g., carboxylic acids, conjugated aromatic phenols/thiols, conjugated aromatic amines, and N‐heterocyclic donors) and metal salts to construct predictable structures with appropriate properties. This review will focus on construction strategies of pristine MOFs and hybrid MOFs as anodes, cathodes, separators, and electrolytes in supercapacitors and batteries. Descriptions and discussions follow categories of electrochemical double‐layer capacitors (EDLCs), pseudocapacitors (PSCs), and hybrid supercapacitors (HSCs) for supercapacitors. In contrast, Li‐ion batteries (LIBs), Lithium‐sulfur batteries (LSBs), Lithium‐oxygen batteries (LOBs), Sodium‐ion batteries (SIBs), Sodium‐sulfur batteries (SSBs), Zinc‐ion batteries (ZIBs), Zinc–air batteries (ZABs), Aluminum‐sulfur batteries (ASBs), and others (e.g., LiSe, NiZn, H+, alkaline, organic, and redox flow batteries) are categorized for batteries.

“…The cells with an FJU‐90 separator can achieve a high areal capacity of 3.96 mAh cm −2 at a current density of 3.1 and 6.2 mA cm −2 with 78 wt.% high sulfur content (Figure 9B). While, Liu et al 93 designed a thermotolerant poly‐ m ‐phenyleneisophthalamide (PMIA)‐based gel polymer electrolyte separator (P‐PMIA@ZIF‐8) by in situ growing ZIF‐8 secondary nanostructures on the P‐PMIA separator (Figure 9C). With abundant multilevel pore structures, the modified P‐PMIA@ZIF‐8 separator exhibited high ionic conductivity.…”

Metal‐organic frameworks (MOFs) integrate several advantages such as adjustable pore sizes, large specific surface areas, controllable geometrical morphology, and feasible surface modification. Benefiting from these appealing merits, MOFs have recently been extensively explored in the field of advanced secondary batteries. However, a systematic summarization of the specific functional units that these materials can act as in batteries as well as their related design strategies to underline their functions has not been perceived to date. Motivated by this point, this review dedicates to the elucidation of diverse functions of MOFs for batteries, which involve the electrodes, separators, interface modifiers, and electrolytes. Particularly, the main engineering strategies based on the physical and chemical features to enable their enhanced performance have been highlighted for the individual functions. In addition, perspectives and possible research questions in the future development of these materials have also been outlined. This review captures such progress ranging from fundamental understanding and optimized protocols to multidirectional applications of MOF‐based materials in advanced secondary batteries.

“…Nanofiber-based separators have better thermal stability, Li-ion conductivity, electrolyte wettability, flexibility, modifiability, and LiPS adsorption ability than standard polyolefin separators. 344 Nonwoven membranes are often made from poly(vinylidene) fluoride (PVDF) 345 or polyimide, 346 and electrospun membranes can be made from various polymers like polyacrylonitrile (PAN) 347 and polyvinylpyrrolidone (PVP). 348 However, such membranes tend to have limited LiPS rejection capabilities and high cost of fabrication.…”
