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. As result, Zn||Zn symmetric cells present an ultra-long cycling lifespan 3 400 h at 1 mA cm-2 700 10 cm-2. Even current density 20 cm-2, demonstrate reversible operations 450 h.
