Abstract Aqueous zinc‐ion batteries (AZIBs) have emerged as a promising energy storage solution owing to their intrinsic safety, low cost, environmental friendliness, and high theoretical specific capacity. However, practical application is hindered by uncontrollable dendrite growth side reactions at the zinc metal anode. To address these challenges, simple cost‐effective electrodeposition strategy proposed construct quaternary Zn‐Cu‐Sn‐Bi alloy artificial interface layer on foil (ZCSB@Zn) anode of AZIBs. Density functional theory (DFT) calculations in situ optical observation confirm that this dense reduces migration barrier weakens hydrogen adsorption, facilitating uniform deposition while effectively suppressing formation. The symmetric ZCSB@Zn cell exhibits extraordinary cycle stability exceeding 8000 h. Furthermore, assembled ZCSB@Zn//CSB‐MnO 2 full demonstrates capacity 199 mAh g −1 1 A , maintaining even under loading 10 mg cm −2 temperature conditions (50 °C). This study presents scalable for constructing layers anodes, highlighting potential AZIB applications.

Abstract Aqueous zinc‐ion batteries (AZIBs) are increasingly recognized as a sustainable and cost‐effective energy storage option, but challenges of zinc dendrite formation, parasitic reactions, corrosion limit their practical use. In this work, monofluorophosphate (ZPOF) is first introduced to modify zinc‐based batteries. The ZPOF exhibits large ionic conductivity 3.8 mS cm −1 , facilitating efficient Zn 2+ ‐ion transport reducing buildup at the zinc/electrolyte interface. Besides, ZPOF's exceptional zincophilic characteristic promotes uniform deposition. ZPOF‐based solid electrolyte membrane enables AZIB offer capacity 322.2 mAh g 0.2 A operate stably for over 500 h 1 . can also be in situ generated on surface form robust conformal coating layer, which prominently enhance affinity, resistance, electrochemical kinetics, while desolvation process restraining ion planar diffusion. As result, Zn//Zn symmetric cell achieves stable cycling 550 under substantial 25 −2 depth‐of‐discharge 85.4%. Furthermore, performance various full‐cell configurations dramatically improved. This study underscores potential novel conductor advancing

Abstract The vulnerable Zn electrode interface with uncontrolled dendrite growth and severe parasitic side reactions constrains the practical application of aqueous zinc‐ion batteries (AZIBs). General engineering offers a promising approach to relieve these issues but is limited by confined functionality, low affinity, additional weight protective layer. In this study, bilayer silane film (SF) developed hydrophobic, ion‐buffering, strong interfacial adhesion properties through precise assembly coupling agents. well‐designed SF layer enables 2+ undergo continuous processes, including being captured –CF 3 groups, followed in sequence inducing desolvation, directed diffusing nanochannels, buffered diffusion. This multiple process contributed accelerated [Zn(H 2 O) 6 ] stabilized transport, inhibited reactions. Consequently, dendrite‐free highly reversible SF@Zn anodes are realized, exhibiting an ultra‐long lifetime (more than 4300 h), high Coulombic efficiency (CE) (99.1% after 2600 cycles), superior full cell capacity retention (83.2% 1000 cycles). innovative strategy provides novel method enhance anode stability via molecular‐level design multicomponent reaction, offering new insights into advanced for AZIBs.
