Abstract The severe dendrite issue of the Zn anode greatly hinders practical application aqueous zinc‐ion batteries, which demands a prompt solution. This work proposes an electrostripping strategy using sodium citrate (SC) solution as electrolyte to fabricate 3D honeycomb‐like (3DH‐Zn) anode. Theoretical calculations and experimental results reveal that SC preferentially adsorbs on Zn(100) Zn(101) planes exhibits shielding effect, leading major dissolution atoms from Zn(002) plane, thus obtaining structure.

Abstract Aqueous Zn batteries have garnered a great deal of attention owing to environmental benefits, intrinsic safety, and cost‐effectiveness. However, the commercial viability these is hindered by anode issues, including dendrite formation side reactions. Herein, authors modulate deposition behavior 2+ ions through 3D ZIF‐8@MXene (Z@M) composite coating. The Z@M coating can effectively reduce contact area with electrolyte, inhibiting hydrogen evolution reaction corrosion.

Abstract Aqueous zinc‐ion batteries (AZIBs) attract attention due to their safety and high specific capacity. However, practical applications are constrained by Zn anode corrosion, dendritic growth, poor high‐temperature adaptability induced a strong hydrogen‐bond network in aqueous electrolytes. In this work, dual polyanionic gel electrolyte (denoted as PAM‐PAMPS‐10PD) is developed capable of withstanding temperatures (100 °C) situ polymerization. The abundant anionic groups the greatly improve 2+ transport inducing uniform deposition . Then addition high‐boiling molecular crowding agent 1,5‐pentanediol (PD) can inhibit water activity enhancing hydrogen bonding with H 2 O changing solvation structure corrosion.
