The coexistence of sluggish Zn<sup>2+</sup> desolvation, competitive H<sub>2</sub>O reduction corrosion, uneven electric field, and concentration field collectively leads to poor rate performance. To tackle these issues, a bolstered interfacial field chemistry strategy was developed via sulfosuccinic acid to precisely regulate the physicochemical and electrochemical properties within the inner Helmholtz plane. The tuned interfacial field comprises a homogeneous distribution of interfacial ions and electric fields, promoting fast desolvation and interfacial electron transfer. Consequently, the modified Zn||Cu asymmetric cells deliver an outstanding average Coulombic efficiency of 99.48% over 1600 cycles at 2 mA cm<sup>−2</sup> and 1 mAh cm<sup>−2</sup>. Furthermore, the modified Zn||Zn symmetric cells demonstrate exceptional stability under challenging conditions of 5 mA cm<sup>−2</sup>, 2 mAh cm<sup>−2</sup> (over 1600 h), and 10 mA cm<sup>−2</sup>, 10 mAh cm<sup>−2</sup> (over 675 h, depth of discharge = 17.08%). Impressively, a substantial cumulative capacity of 3500 mAh cm<sup>−2</sup> is attained at 10 mAh cm<sup>−2</sup> and a 56.93% Zn utilization rate. Besides, the enhanced Zn (10 µm) ||I<sub>2</sub> (10.87 mg cm<sup>−2</sup>) full cell sustains over 1490 cycles at 1 A g<sup>−1</sup> with 77.13% capacity retention and a harsh N/P ratio of 2.31. Remarkably, the Zn (10 µm) ||I<sub>2</sub> pouch cell achieves over 680 cycles with an ultralow N/P ratio of 2.04.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"19 1","pages":""},"PeriodicalIF":36.3,"publicationDate":"2026-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-026-02314-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148615060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
