Angewandte Chemie International Edition, Год журнала: 2024, Номер 63(21)

Опубликована: Март 27, 2024

Abstract Aqueous zinc‐metal batteries (AZMBs) usually suffered from poor reversibility and limited lifespan because of serious water induced side‐reactions, hydrogen evolution reactions (HER) rampant zinc (Zn) dendrite growth. Reducing the content molecules within Zn‐ion solvation sheaths can effectively suppress those inherent defects AZMBs. In this work, we originally discovered that two carbonyl groups N‐Acetyl‐ϵ‐caprolactam (N‐ac) chelating ligand serve as dual sites to coordinate with Zn 2+ , thereby minimizing sheaths, greatly inhibit water‐induced side‐reactions HER. Moreover, N‐ac additive form a unique physical barrier interface on surface, preventing harmful contacting water. addition, preferential adsorption (002) facets promote highly reversible dendrite‐free deposition. As result, Zn//Cu half‐cell added electrolyte delivered ultra‐high 99.89 % Coulombic efficiency during 8000 cycles. Zn//Zn symmetric cells also demonstrated unprecedented long life more than 9800 hours (over one year). Zn//ZnV 6 O 16 ⋅ 8H 2 (Zn//ZVO) full‐cell preserved 78 capacity even after ultra‐long 2000 A practical pouch‐cell was obtained (90.2 100 cycles). This method offers promising strategy for accelerating development efficient

The practical applications for aqueous Zn ion batteries (ZIBs) are promising yet still impeded by the severe side reactions on metal. Here, a lysozyme protective layer (LPL) is prepared metal surface simple and facile self-adsorption strategy. LPL exhibits extremely strong adhesion to provide stable interface during long-term cycling. In addition, strategy triggered hydrophobicity-induced aggregation effect endows with gap-free compacted morphology which can reject free water effective reaction inhibition performance. More importantly, conformation transformed from α-helix β-sheet structure before formation, thus abundant functional groups exposed interact
