Supercapacitors have increased considerable interest due to their unique characteristics such as extended life cycle, high-power density, and environmental friendliness. They serve as a bridge for the energy-power difference between a traditional capacitor and batteries/fuel cells. Selection of the ideal electrode material for a particular application is a critical parameter that affects the efficiency of supercapacitor devices. Transition-metal sulfides exhibit multiple oxidation states and display outstanding supercapacitance performance. Metal sulfides are comparatively superior than metal oxides because of their better conductivity, higher electrochemical activity, and eminent thermal and mechanical stability. A comprehensive summary of the zinc sulfide (ZnS)-based nanomaterials as supercapacitor electrodes is on view. With a band gap of 3.5−3.8 eV, ZnS is one of the first discovered II−VI semiconductors. ZnS has been revealed as a sustainable and promising supercapacitance electrode material owing to its facile synthesis and magnificent electrochemical performance. This review has covered the recent research and development of ZnS nanostructures for supercapacitor electrodes. Additionally, synthesis of ZnS nanostructures and influencing parameters, selection of composite materials, and their design have been summarized for highly efficient supercapacitor devices. As far as our knowledge, this review is the first holistic description of ZnS-based supercapacitor electrodes and devices from basics to recent advancements.

“…For instance, zinc-based materials represent a class of promising and cost-effective electrocatalysts for CO 2 reduction [9] or photoelectrochemical catalysts [10]. Ongoing efforts are currently dedicated to the development of zinc-based materials for applications in energy storage [11], optoelectronics, and nonlinear optics [12][13][14][15][16]. Furthermore, the wellknown biocompatibility and antimicrobial properties of zinc pave the way for innovative biocompatible materials for medical and pharmaceutical applications [17,18].…”

Zn(II) coordination polymers are being increasingly studied for their stability and properties. Similarly, there is a growing interest in imidazo[1,5-a]pyridine derivatives, which show great potential in luminescence and pharmaceutical applications. In this work, we successfully synthesized and crystallized three new coordination polymers, using Zn(II) as the metallic node, dicarboxylic acids of different length and nature as linkers, and a linear ditopic imidazo[1,5-a]pyridine derivative, to explore the role of this molecule as a propagator of the dimensionality of the structure or as an ancillary ligand. Our work demonstrates the structural capability of imidazo[1,5-a]pyridines in an unexplored domain for this family of ligands. Notably, we observed a pronounced ability of this heterocyclic scaffold to establish π···π interactions in the solid state. The supramolecular π-stacked assemblies were theoretically analyzed using DFT calculations based on model structures.

Over the past decade, concerns over the sustainability of lithium‐ion batteries (LIBs) have arisen due to the scarcity of critical elements such as lithium (Li), nickel (Ni), and cobalt (Co), prompting the exploration of alternative and complementary electrochemical energy storage technologies. Due to the more abundant resources compared to contemporary LIBs and the potentially higher specific energy than the emerging sodium‐ion batteries (SIBs), potassium‐ion batteries (PIBs) have attracted intensive research interest as a promising alternative to existing technologies. Nevertheless, the development of practical PIBs remains in its infancy. In this perspective, the various electrode materials and electrolytes reported for PIBs from an application point of view and identifying the most promising ones with high practical interest are first concisely discussed. Then, the pack‐level specific energy, energy density, and cost analyses are presented for several PIBs chemistries, which are also compared with representative LIBs and SIBs to demonstrate the advantages of PIBs. After that, a succinct discussion is presented to evaluate the practicality of potassium metal batteries. Finally, the challenges associated with the commercialization of PIBs, providing future critical research fronts for the development of practical high‐performance PIBs are outlined.
