Steering Interfacial Renovation with Highly Electronegative Cl Modulated Trinity Effect for Exceptional Durable Zinc Anode

Advanced Functional Materials, Год журнала: 2024, Номер unknown

Опубликована: Май 9, 2024

Abstract The poor anode/electrolyte interface triggered by abysmal dendritic growth and hydrogen evolution reactions (HER) hinders the development of aqueous zinc‐ion batteries (AZIBs). Here, a highly efficient electrolyte is formulated with sucralose (Sucral) additive to refresh solvated structure steer interfacial renovation, for building electronegative Cl‐modulated trinity effect in bulk‐interface between electrode. Experiment results theoretical studies jointly reveal that Sucral zincophilic hydrophilic hydroxyl groups can remodel primary Zn 2+ solvation shell interrupt strong H‐bond network from H 2 O molecules, thus boosting fast de‐solvation restricting undesirable HER. Simultaneously, three chlorides adsorbed possessing hydrophobic features enable O‐poor electric double‐layer (EDL), remodeling surface against corrosion. Additionally, it realizes preferential exposure (002) plane helping uniform deposition. synergy above factors achieves prolonged lifespan 3000 h (1.0 mA cm −2 , 1.0 mAh ), much better than Sucrose (Suc) electrolyte. Zn//V 5 full cell at A g −1 also maintains enhanced stability 1500 cycles 160 .

Abstract Aqueous zinc‐ion batteries (ZIBs) are promising large‐scale energy storage devices because of their low cost and high safety. However, owing to the activity H 2 O molecules in electrolytes, hydrogen evolution reaction side reactions usually take place on Zn anodes. Herein, additive‐free PCA−Zn electrolyte with capacity suppressing free solvated was designed by selecting cationophilic solventophilic anions. In such electrolyte, contact ion‐pairs solvent‐shared were achieved even at concentration, where PCA − anions coordinate 2+ bond molecules. Simultaneously, also induce construction H‐bonds between them. Therefore, is effectively restrained. Furthermore, since possess a strong affinity metal Zn, they can adsorb anode surface protect from direct molecules, inhibiting occurrence water‐triggered reactions. As result, plating/stripping behavior anodes highly reversible coulombic efficiency reach 99.43 % electrolyte. To illustrate feasibility Zn||PANI full assembled based exhibited enhanced cycling performance.
