Abstract Aqueous zinc-ion batteries (AZIBs) have been receiving continuous attention as candidates for the next generation of safe batteries, but poor reversibility Zn anode limits their further development. In recent years, researchers obsessed with modifying surface and adjusting solvation structure Zn2+ to address these challenges. Here, we present a novel strategy improve by simultaneously regulating zinc ion flow dividing micro-corrosion zones on anode, thereby manipulating deposition behavior relieving corrosion anode. This approach exploits keto-enol tautomerism α-acetyl-γ-butyrolactone (ABL) develop specifically designed additive: coordinated complex (ZnABL). With this innovative additive, anodes showed excellent reversibility: Zn||Zn symmetric cell achieved long cycle life 7780 h (about 11 months) Coulombic Efficiency averagely reached high value 99.87 %. Furthermore, Zn||Zn0.25V2O5·H2O near-ampere-hour pouch cell, featuring areal capacity 7.9 mAh cm-2, an energy density 106.17 Wh L-1 sustained more than 350 cycles. The success ZnABL in modulating compartmentalizing zone provides option improvement anodes.

Metal–organic assemblies (MOAs), with multiple active sites and well-defined lithium transport pathways, are considered ideal electrode materials for lithium-ion batteries. However, their further development is impeded by poor structural stability limited electronic conductivity. In this study, two isostructural one-dimensional MOAs, namely, [M(pyzdc)(H2O)2]n (M-1D, M = Co Ni; H2pyzdc pyrazine-2,3-dicarboxylic acid) were synthesized storage. The chain structure formed hydrogen bond interactions constitutes a three-dimensional supramolecular architecture. This unique network not only enhances but also facilitates efficient electron transfer. When tested as anode materials, Co-1D Ni-1D exhibited reversible capacities of 1003.3 841.3 mAh g–1 at 100 mA after cycles, respectively. Theoretical calculations kinetic analyses have elucidated the impact configuration on adsorption diffusion in these highlighting intricate relationship between MOAs storage behavior.

Abstract The instability of zinc metal anodes, including dendrite formation and corrosion, limits their application in aqueous zinc‐ion batteries (AZIBs). Here, a near‐single conducting (NSIC) protective layer that enables dendrite‐free Zn anodes by integrating 2 ⁺‐conducting polymer matrices with counter‐anion trapping agents is presented. Sulfonic acid groups, covalently bonded to polymeric backbones enhance ⁺ ion mobility while counter‐anions are immobilized amine‐functionalized metal‐organic frameworks embedded within the layer. This synergistic combination near single transport ( t = 0.91). NSIC extends sand's time promotes uniform deposition along (002) orientation, preventing formation. Consequently, full cells thin Zn@NSIC (14 µm) exhibit stable cycling performance over 5000 cycles at 5 A g⁻¹, low negative‐to‐positive areal capacity (NP) ratio 3.3 depth discharge exceeding 30%. Furthermore, also adapted for enlarged (80 cm ) large‐sized cells, delivering operation ≈300 mAh 1 g⁻¹. These results offer valuable insights into control layers, advancing development practical AZIBs high anode reversibility.
