Abstract Aggressive side reactions and dendrite growth, associated with the unstable Zn anode/electrolyte interface, have impeded practical application of metal‐based batteries. Here, a donor‐acceptor (D‐A) polymer is employed to reconstruct robust supramolecular (SP) protective layer achieve highly stable anodes. The D‐A possessing abundant electron donor acceptor sites can dynamically co‐crosslink water molecules 2 ⁺ through multivalent dipole interactions (MDIs), resulting in formation network. MDIs disrupt original strong hydrogen‐bonding network within polymer, leading reconfiguration chain conformations an increase intermolecular free volume exposing more widely distributed dipoles, thereby regulating 2+ desolvation behavior facilitating rapid uniform plating. Meanwhile, resultant endows SP ultra‐high mechanical modulus 10.4 GPa, which homogenize stress distribution during plating process for effective suppression. Consequently, SP‐assisted asymmetric cell achieves nearly 99.94% Coulombic efficiency over 9000 cycles, enabling Zn/Zn cycle 540 h under ultrahigh 92% utilization. Outstanding cycling stability also successfully demonstrated high mass‐loading (≈12.8 mg cm −2 ) pouch cells, further demonstrating its prospects applications.

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.
