Abstract Despite the conspicuous merits of Zn metal anodes, commercialization anode‐based electrochemical energy storage devices is still constrained by uncontrollable dendrite growth and serious parasitic reactions. Herein, an innovative strategy employing kosmotropic anions‐intensified proline additive to regulate 2+ solvation structure manipulate deposition interface, thus achieving highly stable proposed. The key this lies in ingeniously utilizing SO 4 2− anions enhance affinity adsorption layer on anodes weaken . Consequently, proline‐containing ZnSO (ZnSO ‐proline) electrolyte deliver a remarkable lifespan over 2600 h at 1.0 mA cm −2 mAh Even under harsh plating/stripping condition (10 10 ), ‐proline stably operate for 650 h. Meanwhile, Coulombic efficiency designed as high 99.9% 1100 cycles. endows Zn‐ion batteries hybrid capacitors with notably optimized long‐term cycling stability. This work expected be immediate benefit design low‐cost Zn‐based systems ultra‐long lifespan.

Published: April 8, 2025

Abstract Aqueous zinc‐ion batteries (AZIBs) face challenges in practical applications due to unstable electrode‐electrolyte interfaces and zinc dendrite growth. This study introduces an ultra‐low concentration (5 mmol L⁻¹) zwitterionic additive, Pyridinium‐1‐Propane‐3‐sulfonate (PPS), reconstruct the electric double layer (EDL) regulate surface reactions. Compared with structurally similar ionic additive N‐Butylsulfonicpyridinium (BSO 3 Py) imidazole‐based 3‐(1‐Methyl‐1H‐imidazol‐3‐ium‐3‐yl) propane‐1‐sulfonate (MPS), PPS exhibits superior parallel adsorption on zinc. Its dynamic adaptation Zn 2+ deposition achieves rapid equilibrium, optimizing active site utilization. Sulfonic acid groups form a robust interfacial through intermolecular interactions, while hydrophobic pyridine ring blocks water/sulfate contact. Symmetric achieved 700 hours of cycling at 20 mA cm⁻ 2 cumulative plating capacity exceeding 7000 mAh, alongside 99.81% Coulombic efficiency 5 . Zn‐VO full retained 247.46 mAh g⁻¹ after 1200 cycles A g⁻¹. engineering strategy provides scalable solution for stable AZIBs.
