Abstract The practical application of aqueous Zn‐ion batteries (AZIBs) is hindered by the crazy Zn dendrites growth and H 2 O‐induced side reactions, which rapidly consume anode O molecules, especially under lean electrolyte anode. Herein, a natural disaccharide, d ‐trehalose (DT), exploited as novel multifunctional co‐solvent to address above issues. Molecular dynamics simulations spectral characterizations demonstrate that DT with abundant polar −OH groups can form strong interactions 2+ ions thus massively reconstruct coordination structure hydrogen bonding network electrolyte. Especially, H‐bonds between molecules not only effectively suppress activity but also prevent rearrangement at low temperature. Consequently, AZIBs using DT30 show high cycling stability even (E/C ratio = 2.95 µL mAh −1 ), N/P (3.4), temperature (−12 °C). As proof‐of‐concept, Zn||LiFePO 4 pack LiFePO loading 506.49 mg be achieved. Therefore, an eco‐friendly provides sustainable effective strategy for AZIBs.
