“…In the PP cell, mossy and cumulate lithium dendrites caused by vulnerable SEI and uneven Li deposition can be observed in Figures d and S15d. The Li dendrites will cause a vast surface area and aggravate the electrolyte consumption, resulting in the accumulation of dead lithium and thickening of the SEI. ,,, Hence, the thickness of the loose layer in the PP cell consisting of dead lithium, porous lithium metal, and thick SEI, increased to 188.4 μm (Figure c). As a result, after the 100th cycle, the R SEI increases from 9.97 ohms (after the 50th cycle) to 81.01 ohms (after the 100th cycle) (Figure S15c).…”

For developing the reversible lithium metal anode, constructing an ideal solid electrolyte interphase (SEI) by regulating the Li + solvation structure is a powerful way to overcome the major obstacles of lithium dendrite and limited Coulombic efficiency (CE). Herein, spherical mesoporous molecular sieve MCM-41 nanoparticles are coated on a commercial PP separator and used to regulate the Li + solvation structure for lithium metal batteries (LMBs). The regulated solvation structure exhibits an agminated state with more contact ion pairs (CIPs) and ionic aggregates (AGGs), which successfully construct a homogeneous inorganic-rich SEI in the lithium anode. Meanwhile, the regulated solvation structure weakens the interaction between the solvents and Li + , resulting in low Li + desolvation energy and uniform Li deposition. Thus, a high CE (∼96.76%), dendrite-free Li anode, and stable Li plating/stripping cycling for approximately 1000 h are achieved in the regulated carbonate-based electrolyte without any additives. Therefore, regulating the Li + solvation structure in the electrolyte by employing a mesoporous material is a forceful way to construct an ideal SEI and harness lithium metal.

“…It is primarily combined with features of CVD and hydrothermal methods to further tailor the structure and composition of nanofibers. Electrospinning advantages include (a) mass production of nanofibers with low cost, (b) facile fabrication of controllable nanofiber features in terms of morphology, structure, and composition, and (c) easy acquisition of 3D freestanding membranes [ 16 , 17 , 18 , 19 ]. The fusion of multiple components (carbon materials, [ 20 ], conductive polymers, [ 21 ], metal oxides [ 22 ], etc.)…”

Wearable supercapacitors based on carbon materials have been emerging as an advanced technology for next-generation portable electronic devices with high performance. However, the application of these devices cannot be realized unless suitable flexible power sources are developed. Here, an effective electrospinning method was used to prepare the one-dimensional (1D) and nano-scale carbon fiber membrane based on potassium citrate/polyacrylonitrile (PAN), which exhibited potential applications in supercapacitors. The chemical and physical properties of carbon nanofibers were characterized by X-ray diffraction analysis, scanning electron microscopy, transmission electron microscopy, Raman spectroscopy, X-ray photoelectron spectroscopy, and the Brunnauer–Emmett–Teller method. The fabricated carbon nanofiber membrane illustrates a high specific capacitance of 404 F/g at a current density of 1 A/g. The good electrochemical properties could be attributed to the small diameter and large specific surface area, which promoted a high capacity.

“…The proposed solutions to these issues include reducing the local current density of anodes, planting more seeds for metal deposition, increasing the number of metal ion transfer paths, and improving the shear modulus of electrolytes. [206][207][208] Of these, reducing the local current density of anodes is seemingly the most effective strategy. ZIFs and their derivatives with abundant compositional and structural characteristics are the most suitable candidates for meeting these requirements.…”

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.
