Abstract The application of aqueous zinc‐ion batteries in large‐scale energy storage systems is significantly limited by the hydrogen evolution reaction (HER). Although conventional pH‐adjusting additives can reduce overpotential HER, it imperative to simultaneously modulate composition solid electrolyte interphase (SEI) and electrical double layer (EDL) structure enhance utilization zinc metal. This research develops a multifunctional pH‐controlling additive, bis(2‐hydroxyethyl)amino‐tris(hydroxymethyl)methane (BT). First, addition BT increases pH 5.9, which within its effective buffer zone, reduces HER potential −1.107 V versus Ag/AgCl. Second, inhibitory effect on be further enhanced preferential adsorption molecules containing multiple hydroxyl functional groups anode, leading reduction number active water EDL. Third, participate solvation accomplish reduction, promotes uniform deposition Zn 2+ ions forming nitrogen‐containing SEI. Ultimately, symmetric battery accomplishes 2700 stable cycles BT‐3 electrolyte. More crucially, corresponding Zn//MnO 2 full (1 A g −1 ) able release specific capacity 117.2 mA h after 600 cycles.
