In this study, a low-cost and friendly compound diazolidinylurea carrying number of heteroatoms inter/intra hydrogen bonding, derivative urea (DU), efficiently strengthened aqueous zinc ions batteries (AZIBs) in ZnSO4 electrolyte. The influence DU on the anode 2 M electrolyte was fully studied by various surface chemistry electrochemistry means. It is demonstrated that super low concentration (2 mM, 0.00556 wt %) could inhibit formation dendrites, corrosion, evolution reaction during constant current cycling water system ZIBs, which thus enabled symmetric zinc-zinc to reach cycle life 7336 h (nearly 306 days) under 1 mA·cm-2, mA h·cm-2 at 25 °C 426 18 55 °C, inspired zinc-manganese full battery maintain capacity retention rate more than 52% after for 1000 cycles A·g-1. These results are much superior over ion cells based blank batteries. Even if Zn-Cu half including DU/2 were also pronounced those with bare maximum corrosion inhibition efficiency electrode solution exceeded 82%. Hence, suppression parasitic side reactions, as well growth dendritic crystals addition sulfate electrolyte, played central role intensifying

Abstract Proton insertion mechanism with fast reaction kinetics is attracting more and attention for high‐rate durable aqueous Zn─MnO 2 batteries. However, hydrated Zn 2+ accompanied Jahn–Teller effect Mn 3+ disproportionation generally leads to sluggish rate capability irreversible structure transformation. Here, carboxyl‐carbon nanotubes supported α‐MnO nanoarrays (C─MnO ) cathode successfully fabricated by a convent grinding process high‐performance Specifically, the (CNTs) skeleton endows shorter ion diffusion route active sites proton adsorption, benefiting electron transport reversible evolution of MnO . More importantly, electronegative carboxyl groups Mn─O─C interfacial bonds can effectively restrain dissolution shuttle improved structural integrity redox reactivity. Consequently, C─MnO exhibits high capacity, superior capability, outstanding cycling stability over 10 000 cycles. Even at ultra‐high mass loading (20 mg cm −2 ), Zn//C─MnO punch cell displays excellent capacity (202 mAh) 94.5% retention after 114 cycles, providing new insights practical application advanced Zn‐Mn

Published: April 18, 2025

Aim: Aqueous zinc (Zn)-ion batteries have gained recognition as a promising energy storage solution due to their abundant resources, cost-effectiveness, high density, and inherent safety. However, practical application is significantly limited by issues such dendrite formation parasitic side reactions, which undermine the stability, efficiency, longevity of Zn anodes. Methods: In this study, we present novel approach introducing nanocrystalline nickel-tungsten (Ni-W) coating onto anodes via electrodeposition. This acts functional interface, regulating dissolution deposition, suppressing growth, minimizing reactions. Additionally, W enhances Zn2+ ion adsorption, reduces nucleation barriers, promotes uniform growth along (002) crystallographic plane. Results: The compact morphology Ni-W layer further serves protective barrier, improving electrode stability during extended cycling. Ni-0.1W@Zn anode demonstrates outstanding electrochemical performance, achieving over 2,000 h stable operation at 1 mA cm-2 with Coulombic efficiency 98%. full cell configurations paired Ni-0.1W@Zn||V2O5, system retains 81% its capacity after 1,500 cycles A g-1. Conclusion: These findings highlight transformative potential scalable sustainable address fundamental limitations anodes, paving way for advanced durable technologies critical renewable systems.
