In this study, trace furfural (FF) was introduced into zinc sulfate electrolyte as a nucleophilic ligand to achieve comprehensive water regulation, targeting both interfacial water and the solvated water of hydrated zinc ions. Experimental and theoretical analyses reveal that nucleophilic FF molecules enter the solvation sheath of zinc ions and replace active water molecules, thus suppressing hydrogen evolution. Furthermore, FF molecules induce a water-deficient electric double layer by preferentially adsorbing on the zinc surface, which not only inhibits anode corrosion but also refines zinc crystals, thereby achieving uniform zinc deposition. As a result, the symmetric Zn||Zn cell with FF-ZnSO<sub>4</sub> electrolyte exhibits an extended cycle life and maintains stable of over 2980 h at a current density of 0.5 mA cm<sup>−2</sup>.
