Rechargeable aqueous Zn metal battery demonstrates great potential in grid-type energy storage systems due to its low cost, high safety, and environmental friendliness. However, its practical application is still restricted by Zn dendrite growth and side reactions from the Zn metal anode. Here, we propose a uniform Zn deposition mechanism by optimizing the interface solvation structure using trace isonicotinamide (ISO; only 0.77$/g) as the electrolyte additive. Unlike previously reported acidic additives, which will reduce the electrolyte pH and potentially exacerbate corrosion, ISO molecules do not experience this anxiety. At the same time, ISO can be adsorbed on the surface of Zn electrodes and participate in the dissolution of the structure, adjusting the coordination microenvironment of Zn
