Abstract Achieving stable zinc‐metal anodes is pivotal to realizing high‐performance aqueous batteries (AZMBs). The construction of a functional polymer interface layer on the anode surface confirmed as an effective strategy for mitigating dendrite growth and side reactions, thereby significantly enhancing stability anode. However, polymers capable withstanding electrolyte environments over long term typically suffer from elevated interfacial impedance, which hinders Zn 2+ transport. Here, pioneering enabled by with high‐efficiency ion transport introduced. This polymerized in situ through innovative redox initiation system, where zinc trifluoromethanesulfonate (Zn(OTf) 2 ) salts function both reductant pre‐pathways, ensuring resultant achieves ideal balance ionic conductivity, water resistance, adhesion, mechanical properties, effectively suppressing reactions. Symmetric cells assembled this deliver impressive lifespan 8800 1600 h under 1 5 mA cm −2 , respectively. further demonstrates exceptional feasibility versatility Zn‐NVO Zn‐PANI batteries. work provides groundbreaking insights into strategic design layers AZMBs.

Substantially reducing the platinum (Pt) usage is essential for large-scale application of proton exchange membrane fuel cells (PEMFCs), a key hydrogen-energy technology promising carbon-neutral future. Currently, low-Pt PEMFCs suffer from sluggish reaction and transport kinetics in cathodic catalyst layers (CCLs) caused by adsorption perfluorinated sulfonic acid (PFSA) ionomers to Pt via side chains accompanying uneven PFSA aggregation. Herein, we demonstrate, through detailed physical electrochemical characterizations molecular dynamics simulations, that β-cyclodextrin with unique chemical geometric structure can effectively address these issues molecule assembly route. On one side, forms hydrogen-bonded PFSA, which mitigates sulfonate poisoning Pt, produces ordered hydrophilic domains rapid transport, at same time increases porosity crossing CCL. other hydrophobic nanocavities provide ideal O2 diffusion paths. The thus formed CCL Pt/ionomer interface enriched catalytic sites, well-segregated channels, remarkably boost cell performance.
