Abstract The practical application of aqueous zinc-ion batteries for large-grid scale systems is still hindered by uncontrolled zinc dendrite and side reactions. Regulating the electrical double layer via electrode/electrolyte interface an effective strategy to improve stability Zn anodes. Herein, we report ultrathin zincophilic ZnS as a model regulator. At given cycling current, cell with Zn@ZnS electrode displays lower potential drop over Helmholtz (stern layer) suppressed diffuse layer, indicating regulated charge distribution decreased electric repulsion force. Boosted adsorption sites are also expected proved enhanced double-layer capacitance. Consequently, symmetric protection can stably cycle around 3,000 h at 1 mA cm −2 overpotential 25 mV.

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 performance of aqueous zinc metal batteries is significantly compromised by the stability solid electrolyte interphase (SEI), which intimately linked to structure electrical double layer (EDL) between anode and electrolyte. Furthermore, understanding mechanical behavior SEI crucial, as it governs its response stress induced volume changes, fracture, or deformation. In this study, we introduce l-glutamine (Gln) an additive regulate adsorbed environment EDL in situ produce a hybrid consisting ZnS Gln-related species. results nanoindentation test indicate that exhibits low modulus hardness, alongside exceptional shape recovery capability, effectively limits side reactions enables topological adaptation fluctuations anodes during ion plating/stripping, thereby enabling Zn//Zn symmetric cells exhibit ultralong cycle life 4000 h coin high cumulative capacity 18,000 mA pouch cells.

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
