Abstract Despite aqueous electrolyte endowing batteries with the merits of safe operation, low‐cost fabrication, and high ionic conductivity, water‐induced corrosion, including spontaneous chemical electrochemical hydrogen evolution adversely affects lifespan rate capability. There is still a lack selection criteria for benchmarking corrosion behavior qualitatively. Through theoretical simulation, an anionic polarity index (API) tactic proposed to resist by manipulating interfacial solvated water concomitantly, thus realizing stable fast Zn (ZABs). As proof concept, zinc salt 0.5 m bis(4‐hydroxybenzenesulphonate) (Zn(HBS) 2 ) low‐API anion prioritized. Combined in situ spectroscopic analyses reveal that, even low‐concentration electrolyte, reduces inner Helmholtz plane, shielding dissociation. Meanwhile, their entering into solvation sheath 2+ lowers solvent‐separated ion pair, suppressing corrosion. The elaborated API‐screened endows plating kinetics 50 mA cm −2 (119.1 mV polarization), coulombic efficiency 99.8%, dendrite‐free cycling over 1600 h, prolonged 5000 cycles Zn‐V cell. results provide new metrics that can benchmark success ZABs large‐scale energy storage.
