Abstract Regulating the H‐bond network between H 2 O molecules has been regarded as an effective strategy to reconfigure chemical environment at electrode/electrolyte interface (EEI), but intrinsic relationship hydrogen‐bond (H‐bond) network, solvation structure, and EEI in electrolyte remains unclear. To this end, three additives with same carbon skeleton different hydroxyl functional groups are chosen unlock their triangular relationship. Experimental theoretical calculations demonstrate that 2‐methyl‐1,3‐propanediol (MP) bearing strong kosmotropic effect modest steric‐hindrance not only form a stable H‐bonds by breaking original of also reconstruct structure Zn 2+ , predominantly inhibiting O‐triggered side reactions. Meanwhile, synergistic direction on MP ensures adsorption EEI, promoting uniform diffusion deposition. Consequently, assembled Zn||Zn symmetric cell provides 3000 h cycle life (0.5 mA cm −2 0.5 mAh ) ZnSO 4 +MP electrolyte, Zn||Cu asymmetric maintains high CE 99.41% after 1000 cycles 1 .

Abstract Zn dendrite growth and parasitic reactions at the interface of zinc anode/electrolyte in aqueous batteries severely hinder its lifespan application. Herein, anode is effectively stabilized by introducing trace amounts 4‐aminobutane‐1‐phosphate (ABPA) into ZnSO 4 electrolyte. The ABPA adsorbs onto surface then further decomposes to a high conductive organic/inorganic composite situ SEI layer including amino, partial carbon chain, phosphate. In layer, residual undecomposed chain promotes desolvation 2+ , amino induces uniform plating phosphate facilitates migration . Thus, this not only suppresses water‐related side but also enhances transport kinetics. As result, Zn||Zn symmetric cell delivers an ultralong cycle life over 13 000 cycles 50 mA cm −2 1 mAh A average Coulombic efficiency 99.72% achieved 1000 Zn||Cu half‐cell.
