Abstract Aqueous zinc ion batteries (AZIBs), which have attracted attentions in the field of energy storage, is affected by dendrites and side reactions Zn anode, resulting an unsatisfactory performance AZIBs. Herein, we propose a biased adsorption strategy mediated straight‐chain molecule (Scm) for stabilizing anode. The dual polar termini Scms guaranties securely anchor themselves parallel orientation upon anode surface. This provides comprehensive coverage, effectively sequestering water molecules from precipitating formation water‐depleted electric double layer (EDL). Furthermore, selectively adsorb along crystallographic planes, guiding deposition 2+ . Consequently, incorporation these successfully mitigates corrosion, HER, dendrites. Zn||Zn, Zn||Cu Zn||V 6 O 13 cells with display significantly enhanced electrochemical performance, especially at elevated temperature 60 °C. work highlights potential cost‐effective, electrolyte additives enhancing stability.

Abstract The large‐scale application of low‐cost and environmentally‐compatible aqueous Zn‐ion batteries (AZIBs) is largely hindered by the Zn dendrite growth stemming from inhomogeneous deposition. To tackle this challenge, 4‐(2‐hydroxyethyl)‐1‐piperazineethanesulfonic acid introduced as electrolyte additive to in situ construct ordered self‐assembled monolayers on anode (Zn@HEPES), providing uniform active sites 2+ nucleus regulators that can be dynamically spontaneously replenished according environmental conditions. Meanwhile, because regulated solvation sheath hydrophobicity Zn@HEPES, direct contact between water molecules effectively ameliorated, which promotes transport deposition kinetics. above synergistic effects enable highly reversible redox chemistry achieve a dense electrodeposition with suppressed growth. Consequently, thus‐derived Zn||Zn symmetric cells exhibit an excellent long‐term stability for 4000 h at current density 1 mA cm −2 . Additionally, aid full coupling MnO 2 cathode also demonstrate superior reaction reversibility capacity retention. This work demonstrates distinctive avenue molecular level precisely regulating process practical AZIBs.
