Aqueous zinc metal batteries (AZMBs) are promising candidates for next-generation energy storage due to the excellent safety, environmental friendliness, natural abundance, high theoretical specific capacity, and low redox potential of (Zn) metal. However, several issues such as dendrite formation, hydrogen evolution, corrosion, passivation Zn anodes cause irreversible loss active materials. To solve these issues, researchers often use large amounts excess ensure a continuous supply materials anodes. This leads ultralow utilization squanders density AZMBs. Herein, design strategies AZMBs with discussed in depth, from utilizing thinner foils constructing anode-free structures 100%, which provides comprehensive guidelines further research. Representative methods calculating depth discharge different first summarized. The reasonable modification foil anodes, current collectors pre-deposited Zn, aqueous (AF-AZMBs) improve then detailed. In particular, working mechanism AF-AZMBs is systematically introduced. Finally, challenges perspectives high-utilization presented.

Abstract As a new generation of lithium‐ion battery alternative, aqueous zinc (Zn) ion batteries (ZIBs) garner tremendous interests for future energy storage application owing to their inherent incombustible, nontoxic, and low‐cost features. However, practical utilization is hampered by the electrolyte freezing at subzero conditions. In this study, novel high‐entropy (HE) fabricated presented with hybrid solvents mitigate low temperatures, restrain calendar corrosion, boost Zn‐ion transfer kinetics. Specifically, isovolumetric combined ethyl acetate, ethylene glycol, dimethyl sulfoxide as solvent components not only induce reconfiguration hydrogen bonding, but also alter solvation sheath Zn ions within HE environment. This synergistic coupling co‐solvents effectively harnesses features individual additive facilitates remarkable advantages on cycling reversibility, especially in low‐temperature Benefiting from anti‐freezing structure regulation features, symmetrical equipped electrolytes can work over 2500 h salt concentration (1 m ) various temperatures. provides facile modulation strategy achieve electrolyte, promoting commercialization advanced ZIBs wide‐temperature adaptability.

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.
