To address these challenges, we present a molecular engineering strategy that modulates the highest occupied molecular orbital (HOMO) energy levels through rational structural design. Three novel thiophene-functionalized pyrene-4,5,9,10-tetrone derivatives—2,7-di(thiophen-3-yl)pyrene-4,5,9,10-tetraone (PTO-3TP), 2,7-di(thiophen-2-yl)pyrene-4,5,9,10-tetraone (PTO-2TP), and 2,7-di([2,2′-bithiophen]-5-yl)pyrene-4,5,9,10-tetraone (PTO-BITP)—are designed by strategically tailoring the junction position and number of thiophene bridging units. This structural optimization significantly elevates the HOMO energy levels and enhances the π-conjugation, thereby synergistically boosting the p-type redox activity. Notably, after electropolymerization, the products exhibit further elevated HOMO levels and reduced energy gaps, enabling superior charge transfer kinetics. Specifically, the electropolymerized PTO-BITP cathode demonstrates exceptional electrochemical performances including a high reversible capacity of 280 mAh g<sup>-1</sup> at 0.2 A g<sup>-1</sup> over 500 cycles, remarkable rate capability (120 mAh g<sup>-1</sup> at 10 A g<sup>-1</sup>), and ultrahigh cycling stability (100 mAh g<sup>-1</sup> retained after 5000 cycles at 5 A g<sup>-1</sup>).

These challenges are closely related to electrolyte solvent and ion transport behavior, which are expected to be resolved through meticulous separator design. In nature, the enzyme-gated ion channels in biological cell membranes facilitate selective ion transport with rapid desolvation, through their specific pore size and enzymatic gating mechanisms. Herein, inspired by intricate structure-function relationship of the enzyme-gated ion channels, we propose a lightweight and mechanically stable separator composed of bacterial cellulose and vermiculite. This separator demonstrates a synergistic effect that enhances selective transport and desolvation kinetics of Zn<sup>2+</sup> while trapping active H<sub>2</sub>O in its bulk phase. This promotes uniform Zn<sup>2+</sup> diffusion and creates a stable, H<sub>2</sub>O-deficient electrolyte environment at electrode interfaces. Such separator enables Zn anodes to achieve a lifespan exceeding 7000 hours (3500 cycles) with a high average Coulombic efficiency of 99.77 %, and allows the Mn<sub>0.5</sub>V<sub>6</sub>O<sub>13</sub> cathode (4 mAh cm<sup>−2</sup>) with excellent self-discharge resistance and superior cycling performance with 89.4 % capacity retention over 500 cycles at 0.3 A <em>g</em><sup>−1</sup>. Notably, full cell using this separator exhibits remarkable cycling stability for over 400 cycles at a low N/P ratio of 4.4. This innovative separator not only signifies substantial advancements toward practical application of AZMBs, but more importantly, its design concept inspired by nature, from biomimicry to beyond biomimicry, provides valuable insights for future material development.</div></div>","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"79 ","pages":"Article 104311"},"PeriodicalIF":18.9,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143927066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
