The commercialization of high‐energy‐density alkali metal (Li, Na, and K)–chalcogen (S, Se, and Te) batteries (AMCBs) has been primarily hindered by the volume expansion of chalcogen cathodes during repeated charging/discharging cycles, the shuttling effect of intermediates in the electrolytes, and unstable alkali metal anodes. Owing to their unique structural and physicochemical characteristics, including high specific surface areas, self‐doped N atoms, open pore structure, versatile compositions, and favorable chemical stability, zeolitic imidazolate frameworks (ZIFs) and their derivatives have been widely used in different battery components, such as cathodes, anodes, separators, and interlayers, to resolve these issues simultaneously. This review discusses recent advances in ZIFs and their derivatives for cathode construction, anode protection, and interlayer/separator design in AMCBs. The processing methods, structure and morphology engineering, composition tuning, and electrochemical performance of various ZIFs and their derivatives are systematically examined. More importantly, the remaining challenges and future research directions are summarized and discussed. This review is expected to offer new approaches for the rational design of ZIFs and their derivatives for emerging energy storage devices.

“…In Shen's report (Xiao et al, 2019), they found during the annealing process that the cobalt atoms will coordinate with N atoms to form Co 4 N. Because the electron transferred from Co to the doped N in the carbon matrix, this caused a larger polarization of Co in Co 4 N. This synergistic effect between Co and doped N can contribute to increased binding energy between Co 4 N and polysulfides (Xiao et al, 2019). Moreover, using the Co-decorated carbon materials as an interlayer or to modify the separator has also been widely reported (Chen et al, 2018a;Zhang et al, 2019c;Li et al, 2020d;Jiang et al, 2020;Song et al, 2020).…”

Lithium-sulfur (Li-S) and lithium-selenium (Li-Se) batteries are both facing the cathode issues of low Coulombic efficiency and unstable cycling stability due to the severe shuttle effect of lithium polysulfides or lithium polyselenides. Simultaneously inhibiting polysulfides/polyselenides dissolution in organic electrolytes and propelling them to conversion via introducing polar, catalytic materials has been proven as an effective strategy to enhance the durability of Li-S and Li-Se batteries. In this mini review, we systematically introduce various metal atom-decorated carbon nanomaterials to determine how to enhance the electrochemical performances of Li-S and Li-Se batteries by inhibiting the polysulfides/polyselenides shuttle phenomenon as well as catalyzing them toward quick redox conversions. We also briefly include the drawbacks and bottlenecks of this kind of material when used in Li-S and Li-Se batteries

The sulfur cathode of lithium‐sulfur (Li‐S) batteries suffers from inherent problems of insufficient mechanical strength and the dissolution of sulfur and polysulfides. Inspired by the extraordinarily resilient and strong binding force of the Great Wall binder, that is, the sticky rice mortar, we extracted highly branched amylopectin (HBA), the effective ingredient, as a low‐cost, nontoxic and environmentally benign aqueous binder for the sulfur cathode. The HBA‐based cells outperform the Li‐S batteries based on the traditional polyvinyldene diflouride (PVDF) binder and a lowly branched polysaccharide binder. The improved electrochemical performance in the HBA‐based cell could be attributed to two mechanisms. First, the branched structure of the HBA provides enhanced mechanical and adhesive properties, which allow for a robust electronic and ionic conductive framework to be maintained throughout the cathode after extended cycling. Second, the HBA shows enhanced polysulfide retention due to the polymer's abundant lone‐pair rich hydroxyl groups and the formation of C─S bonds between the HBA and polysulfides prohibits the shuttle effect of polysulfides. The improved mechanical properties and polysulfide retention function of the HBA binder facilitate the HBA‐based Li‐S battery to deliver a long cycle life of 500 cycles at 2 C while only displaying a capacity fading of 0.104% per cycle.
