Abstract Aqueous zinc‐ion hybrid capacitors (ZIHCs) are emerging as promising energy storage devices owing to several desirable attributes including good safety, high power density, and stability. However, the limited density mainly caused by low specific capacity of porous carbon cathodes hinders practical application ZIHCs. A Ce 3+/4+ redox couple‐promoted aqueous ZIHC (Ce‐ZIHC) is designed with addition electrolyte additives. The couple shown markedly increase cathode enhance stability Zn 2+ stripping/plating at metal anode. Notably, as‐constructed Ce‐ZIHC performs more than twice commercial activated cathode. Furthermore, shows a self‐discharge rate can work stably for 60 000 cycles 5.0 g −1 . This highlights great potential in improving overall performance ZIHCs toward application.

With the over-consumption of non-renewable energy, green and clean renewable energy is inevitably choice in modern society. In particular, lithium-ion batteries (LIBs) have been widely used automobiles, aviation other fields due to their high density advantages. However, lithium reserves are limited, LIBs safety hazards, so development alternative rechargeable cannot be delayed. Aqueous zinc ion (AZIBs) a theoretical specific capacity while ensuring safety, intensively investigated recent years. The advancement cathode materials essential for AZIBs. this article, non-oxide manganese vanadium such as MnS, MnHCF, VN, VSe2 VS2 AZIBs critically reviewed. emerging strategies modifying these enhanced electrochemical performance analyzed. Finally, some important achievements research field summarized, challenges future directions presented. We hope that article can shed light on

Van-der-Waals hosts intercalated with transition-metal (TM) ions exhibit a range of magnetic properties strongly influenced by the structural order intercalants. However, predictive computational models for intercalant ordering phase diagram are lacking, complicating experimental pursuits to target key phases. Here we use density functional theory (DFT) construct pairwise lattice model and Monte Carlo determine its associated thermodynamic diagram. To circumvent complexities modeling effects, diamagnetic Zn2+ Sc3+ as computationally accessible proxies divalent trivalent species interest (Fe2+, Co2+, V3+ Cr3+), which provide insights into well above paramagnetic transition temperature. We find that electrostatic coupling between intercalants is almost entirely screened, so represents coarse-grained charge reorganization. The resulting reveals entropically favored √3 × coexisting locally ordered 2 domains persist across temperatures stoichiometries. This occurs even at quarter-filling interstitial sites (corresponding bulk stoichiometries M0.25TaS2; M = intercalant) where there reports coexistence but preference long-range often assumed. Accompanying Raman spectra revealing quenching-induced in 2H-V0.25NbS2 supports deficient may dominate high TM-intercalated metal dichalcogenides.
