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.
