Abstract The performance of aqueous zinc‐ion batteries (AZIBs) at high temperatures (HT) is severely compromised by active water corrosion, parasitic reactions, and dendrite growth. Herein, zinc trifluoroacetate introduced a low concentration (0.2 m ), dissolved in triethyl phosphate (TEP)and H 2 O. suppressed due to the reconstructed original hydrogen bond network, which helps inhibit reactions severe corrosion. Meanwhile, solid electrolyte interphase (SEI) formed on anode decomposition salt. high‐tolerance SEI physically separates anode, reducing corrosion caused water. Moreover, TEP, as prevalent fire‐retardant cosolvent, can preferentially anchor sheet, serving shielding buffer layer. TEP not only reconstructing structure electric double layer (EDL), decreasing content water, but also accelerating prompt formation further. As proof this synergistic effect, assembled symmetric Zn.
