Abstract The advancement of aqueous zinc‐ion batteries (AZIBs) faces significant obstacles due to the typically loose and unstable solid electrolyte interphase (SEI), which fosters dendrite formation undermines cycling performance, especially in cold environments. Here, a quasi‐high‐entropy (QHE‐SEI) formulated is introduced with diverse functional inorganic compounds, achieved through incorporation dual salts blend solvents. Shielded by QHE‐SEI, AZIBs exhibit uniform zinc deposition attain remarkable stability, enduring for 1300 h Zn||Zn symmetric cells under conditions 3 mA cm −2 mAh at room temperature. Furthermore, full cell maintains over 4300 cycles −20 °C nearly capacity retention. Notably, pouch high ≈25 across 50 cycles, even °C. This study offers novel approach designing stable SEI elevates performance AZIBs.
