“…It could reach a high discharge capacity of 1131.3 mAh/g at 0.5 C and maintain a capacity of 873.9 mAh/g after the 300th cycle with the capacity retention of 77.2 %. [98] Furthermore, MOFs with low conductivity also hinder the further utilization of MOF in LiÀ S battery. Composites prepared by hybridizing MOFs with other conductive materials have been designed to improve the conduction of MOFs.…”

Currently, lithium sulfur (Li‐S) battery with high theoretical energy density has attracted great research interest. However, the diffusion and loss process of intermediate lithium polysulfide during charge‐discharge hindered the application of the Li‐S batteryin modern life. To overcome this issue, metal organic frameworks (MOFs) and their composites have been regarded as effective additions to restrain the LiPS diffusion process for Li‐S battery. Benefiting from the unique structure with rich active sites to adsorb LiPS and accelerate the LiPS redox, the Li‐S batteries with MOFs modified exhibit superior electrochemical performance. Considering the rapid development of MOFs in Li‐S battery, this review summarizes the recent researches of MOFs and their composites as the sulfur host materials, functional interlayer, separator coating layer, and separator/solid electrolyte for Li‐S batteries in detail. In addition, the promising design strategies of functional MOF materials are proposed to improve the electrochemical performance of Li‐S battery.

“…As seen from Figure 6, the separator possessed a unique fibrous network, which effectively reduced the shuttle effect of LiPS, resulting in a high initial capacity of 1125 mA h g −1 at a good Coulombic efficiency of 98% over 300 cycles. Lin et al 92 adopted UiO-66 as the host MOF to wrap lithium sulfonate in the ordered pores, thus forming UiO-66(SO 3 Li) 4 with rich −SO 3 Li groups. It was indicated that the enhanced electronegativity and lithium ion conductivity effectively prevented the shuttle effect of polysulfides and significantly boosted the discharge capacity, rate capability, and cycling stability.…”

With the continuous growth of global energy demands and the increasingly serious environmental problems, the catalytic conversion and storage technology of sustainable energy has attracted more attention. Among the current energy storage methods, electrochemical energy storage (EES) is favored due to its high efficiency, stability, and environmental friendliness. In the development of EES devices, batteries and supercapacitors are the two most effective and attractive types. Metal−organic frameworks (MOF), as an emerging class of ordered crystal materials, are becoming highly promising electrode materials due to their adjustable topology structures, functionality, porosity, and electrocatalytic performances. The low conductivity seriously hinders the application of pristine MOFs in the field of energy storage, and a large number of MOF-based materials have been developed to meet the challenges of energy storage and conversion. Thus, the current review focuses mainly on the use of MOF-based materials (including pristine MOFs, MOF composites, and MOFderivatives) for EES, especially as electrode materials for metal-ion batteries and supercapacitors, and addresses the influence of material structures on electrochemical performances. Finally, we introduce the current challenges and improvement strategies of MOF-based electrode materials, pointing out the direction for developing electrode materials with industrial application value.

“…In comparison to these manners, it is a more facile approach to modify the separator with appropriate materials, such as conductive carbon materials, , metal oxide, , transition metal sulfide, , and metal–organic frameworks, , to enhance the performance of LSBs. As an integral component of Li–S batteries, the separator’s main functions are to prevent direct contact between the positive and negative electrodes and allow ion transmission.…”

The Li−S battery has garnered widespread attention as an intriguing new energy storage equipment due to its remarkable energy density and low cost. Nevertheless, the infamous shuttle effect seriously hinders the commercialization process. In order to address this issue, this study rationally synthesizes the composites comprising Keggin-type polyoxometalate and Co nanoparticles, which are then coated on a pristine polypropylene separator. The modified separator can greatly inhibit lithium polysulfide shuttling, thereby leading to a greatly improved electrochemical performance. At the first cycle, the fabricated Li−S battery exhibits a specific discharge capacity of 1335.7 mA h g −1 , surpassing the 938.7 mA h g −1 capacity of an unmodified separator. At a current density of 1C, the initial reversible discharge capacity reaches 988.2 mA h g −1 , and even after 500 cycles, it still retains a remaining capacity of 664.2 mA h g −1 , with a capacity decay rate of 0.066% per cycle. Even at a high sulfur loading of 4.2 mg cm −2 , the device displays a remarkable initial discharge capacity of 1158.2 mA h g −1 , with a remaining capacity of 952.7 mA h g −1 after 70 cycles (0.1C). This significant performance enhancement could be ascribed to the synergistic effect of PMo 12 /Co−NCe, which exhibits greatly decreased electron transfer resistance and contact angle to the electrolyte, facilitating the rapid transport of Liion and kinetics. Meanwhile, the severe shuttle effect is alleviated effectively by combining the strong catalytic activity of PMo 12 and Co nanoparticles with long-chain polysulfides.
