Abstract The stability of aqueous zinc metal batteries is significantly affected by side reactions and dendrite growth on the anode interface, which primarily originate from water anions. Herein, we introduce a multi H‐bond site additive, 2, 2′‐Sulfonyldiethanol (SDE), into an electrolyte to construct sieving‐type electric double layer (EDL) hydrogen bond interlock in order address these issues. On one hand, SDE replaces H 2 O SO 4 2− anions that are adsorbed surface, expelling O/SO EDL thereby reducing content at interface. other when Zn 2+ de‐solvated interface during plating, strong interaction between can trap EDL, further decreasing their This effectively sieves them out inhibits reactions. Moreover, unique characteristics trapped restrict diffusion, enhancing transference number promoting dendrite‐free deposition Zn. Consequently, utilizing SDE/ZnSO enables excellent cycling Zn//Zn symmetrical cells Zn//MnO full with lifespans exceeding 3500 h 2500 cycles respectively.
