However, their practical implementation is significantly hindered by interfacial side reactions, particularly the hydrogen evolution reaction (HER) at the Zn metal anode interface. Herein, this study presents an innovative approach to address this challenge through the construction of an interfacial preferential coordination layer on the Zn anode surface. The proposed layer effectively terminates the continuity of interfacial hydrogen-bond networks and blocks proton transport, thereby mitigating the HER. Specifically, 2-phenylbenzimidazole-5-sulfonic acid (PBSA) with zincophilic groups was introduced as an electrolyte additive, which would be preferentially and selectively anchored on the Zn surface through its zincophilic nitrogen and sulfonic acid, forming the interfacial coordination layer. This coordination layer serves as a protective barrier, repelling water molecules from the Zn electrode surface and alleviating water decomposition. Crucially, the interfacial coordination layer features stronger hydrogen-bonding interactions with interfacial water molecules, terminates the hydrogen-bonding network between water molecules, hinders the transportation and electro-reduction of proton, and ultimately inhibits HER at the interface.

Above 60 °C, Zn begins to grow vertically on the substrate, forming larger particles and intensifying side reactions. These differences in Zn growth behaviors at varying temperatures are closely linked to changes in Zn nucleation, as observed through in situ atomic force microscopy. Consequently, elevated temperature in a ZFB promotes preferentially vertical deposition of Zn at the membrane/electrode interface, extending into the membrane.

The full cell of ZIS/C||Na<sub>3</sub>V<sub>2</sub>(PO<sub>4</sub>)<sub>3</sub> exhibits excellent high-rate capability (178 mA h g<sup>−1</sup> at 6A g<sup>−1</sup>).</div></div>","PeriodicalId":15728,"journal":{"name":"Journal of Energy Chemistry","volume":"107 ","pages":"Pages 386-392"},"PeriodicalIF":13.1,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143855076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
