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. Notably, theoretical calculations in situ experimental observations reveal that dual coordination mechanism MXene ZIF‐8 significantly improves adsorption energy atoms. This improved capacity capture will promote desolvation hydrated ions, resulting dendrite‐free process. Therefore, symmetry cell, Z@M‐Zn demonstrates an impressive cycle life 1050 h at 1 mA cm −2 .

Abstract The inhomogeneous dendrite growth and parasitic side reactions of Zn anodes as well its sluggish solvation/de‐solvation kinetics severely hinder the practicalization fast charging Zn‐ion batteries. Regulating electric double layer (EDL) structure is an effective strategy to address these issues. Herein, a perovskite dielectric ZnTiO 3 (ZTO) designed on anode construct autoregulative EDL for achieving capability. ZTO can spontaneously generate surface charge with external voltage regulate structure, which results in increased/decreased capacitance under plating/stripping potential respectively, leading promoted 2+ rapid reaction kinetics. Meanwhile, H 2 O‐insufficient environment created by self‐regulated uniform field prevent during deposition process. Attributed feature, ZTO@Zn exhibits excellent cycle stability over 2850 h at 1 mA cm −2 symmetrical cells. Even high current density 50 , it still stable 230 h. Additionally, assembled ZTO@Zn//AC supercapacitor demonstrates ultralong lifetime 140 000 cycles 5 A g −1 . This work provides regulation realize capability metal practical application.
