Abstract Developing artificial protective layers is an effective strategy to address the issue of dendrites for aqueous Zn‐metal batteries (ZMBS). However, drawbacks such as rough microscopic morphology, excessive thickness, and single functionality remain, limiting attainment a stable zinc anode. Herein, novel multifunctional organic–inorganic hybrid layer produced by splicing inorganic fragments onto organic materials in situ using chemical sewing. The well‐compatible also retains function materials, which not only inhibits dendrite production but alleviates Zn corrosion. Si─OH bond zincophilic group enables planar deposition while forming hydrogen bonds with water, suppressing water activity near anode reducing evolution reaction. As expected, Zn||Zn symmetric cell provides high cycling stability more than 1960 h at 1 mA cm −2 , about 28 times higher that assembled without layer. More importantly, Zn||V 2 O 5 full ultra‐long lifetime has been achieved This work potential viable path achieve long‐lived ZMBS.

Aqueous Zn metal batteries are considered promising energy storage devices due to their high density and low cost. Unfortunately, such great potential is at present obscured by two clouds called dendrite growth parasitic reactions. Herein, trace amounts of sodium cyclamate (CYC-Na) introduced as an electrolyte additive, accordingly, atomic-pinning-induced interfacial solvation mechanism proposed summarize the effect addition. Specifically, coadsorption -NH- -SO3 groups overcomes ring-flipping pins CYC anion near anode surface in parallel, which significantly modifies Zn2+ sheath interface. This process homogenizes flux reduces H2O SO42- content on surface, thus eliminating byproducts leveling deposition. Cells with CYC-Na cycle stably for 3650 h still 330 depths discharge 56.9%. work dispels efficient additives AZMBs.

Опубликована: Май 3, 2024

Abstract Metal Zn anode encounters uncontrolled dendrite growth, resulting in poor cycling stability and low coulombic efficiency (CE). Herein, a novel approach for oriented‐electrochemical etching of (ECE‐Zn) deep eutectic solvent (DES) is presented to adjust the interface concentration electric fields, effectively mitigating intractable issues. The oriented etches off crystal edges between (002), (100), (101) principal planes commercial foil, subsequently (100) planes, formation well‐organized columns. Comprehensive experimental investigations theoretical analyses reveal that ions directionally nucleate grow columns, enabling epitaxial growth at (002) plane. ECE‐Zn‐2 anodes demonstrate remarkable stability, along with nucleation polarization voltages. Specifically, symmetric cells show sustained operation 5400 h, long‐term 10 000 cycles 40 mA cm −2 . More significantly, asymmetric exhibit an average CE as high 99.92% over 6000 5.0 When assembled V 2 O 5 cathode, retention 81.5% can be maintained even under severe condition (N/P ratio 7.35). This strategy opens up new pathway dendrite‐free metal anode.
