“…[18] Metal-organic frameworks (MOFs) with a very large density of LiPS adsorption sites have a huge potential as sulfur hosts. [19,20] The Lewis acid-base interactions between MOFs and LiPS have been demonstrated to effectively restrain the migration of LiPS, thus improving the LSB performance. [21,22] Besides, their large structural and chemical diversity provide numerous degrees of freedom to optimize their performance.…”

The shuttling behavior and sluggish conversion kinetics of the intermediate lithium polysulfides (LiPS) represent the main obstructions to the practical application of lithium–sulfur batteries (LSBs). Herein, a 1D π–d conjugated metal–organic framework (MOF), Ni‐MOF‐1D, is presented as an efficient sulfur host to overcome these limitations. Experimental results and density functional theory calculations demonstrate that Ni‐MOF‐1D is characterized by a remarkable binding strength for trapping soluble LiPS species. Ni‐MOF‐1D also acts as an effective catalyst for S reduction during the discharge process and Li2S oxidation during the charging process. In addition, the delocalization of electrons in the π–d system of Ni‐MOF‐1D provides a superior electrical conductivity to improve electron transfer. Thus, cathodes based on Ni‐MOF‐1D enable LSBs with excellent performance, for example, impressive cycling stability with over 82% capacity retention over 1000 cycles at 3 C, superior rate performance of 575 mAh g−1 at 8 C, and a high areal capacity of 6.63 mAh cm−2 under raised sulfur loading of 6.7 mg cm−2. The strategies and advantages here demonstrated can be extended to a broader range of π–d conjugated MOFs materials, which the authors believe have a high potential as sulfur hosts in LSBs.

Both configuration match and electronic structure are vital for catalysts to efficiently promote the conversion of lithium polysulfides (LiPSs) in lithium−sulfur batteries (LSBs), which are however difficult to tailor in traditional catalysts that generally have a single active center. Herein, a series of dual-active-center MOFs (D-MOFs) were elaborated to manipulate the distance between different polar active sites and regulate the electronic structure of the metal center, which can match the configuration of long-chain LiPSs and optimize the metal−sulfur orbital hybridization. Moreover, in situ axial assembly of customized D-MOFs on carbon nanotubes delivers hierarchical sulfur hosts, which can remarkably improve the LSB performance, realizing high areal capacity (10.04 mAh cm −2 ) under high sulfur loading and lean electrolytes, and a pouch cell with high energy density (310.7 Wh kg −1 ). This work gives insight into the multiscale design of multifunctional catalytic MOFs, promising advancements in catalyst development for high-performance LSBs.

“…Integration of MOFs, constantly investigated as hosting species, with sulfur and conducting species such as Super-P carbon, [76,[401][402][403][404][405][406][407][408][409][410] N,P codoped carbon, [411] graphene, [412] CNTs, [403,406,[413][414][415][416] polypyrrole, [98,417,418] to apply as cathodes in LSBs have been heavily explored. For instance, a defective Zr MOF (UiO-66) induced by modulators of benzoic acid followed by deprotonation and lithiation was prepared to integrate with Super-P carbon, sulfur, and a binder PVDF as MOF composite cathodes (Figure 15a).…”

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.
