Abstract Zn metal anodes (ZMAs) are plagued by dendritic growth and side reactions, which results in the degradation of their electrochemical performance. In this study, a carboxylated pillar[5]arene (CP5) is introduced with Janus properties to reconstruct solvation structure 2+ modulate inner Helmholtz plane (IHP). The electron‐rich cavity CP5 adsorbs through electrostatic interactions synergistically reconfiguring solvated Zn. Concurrently, zincophilic carboxyl groups preferentially adsorb onto electrode interface, while hydrophobic modulates IHP repelling certain H₂O molecules. synergistic impact dual reconfiguration strategy effectively suppresses hydrogen evolution reaction (HER), curtails dendrite formation associated thereby enhancing long‐term stability electrode‐electrolyte interface. demonstrate that Coulombic efficiency (CE) 99.1% Zn||Cu asymmetric cell achieved during galvanization/stripping process at 5 mA cm −2 under 1 mAh .

Aqueous zinc ion batteries (AZIBs) face challenges due to the limited interface stability of Zn anode, which includes uncontrolled hydrogen evolution reaction (HER) and excessive dendrite growth. In this study, a natural binary additive composed saponin anisaldehyde is introduced create stable interfacial adsorption layer for protection via reshaping electric double (EDL) structure. Saponin with rich hydroxyl carboxyl groups serves as "anchor points", promoting through intermolecular bonding. Meanwhile, anisaldehyde, unique aldehyde group, enhances HER suppression by preferentially facilitating electrocatalytic coupling H* in EDL, leading formation robust inorganic solid electrolyte interphase that prevents formation, structural during deposition process verified.
