Abstract Dendrite growth and parasitic side reactions on zinc (Zn) metal anode are major challenges limiting the practical application of aqueous ion batteries (AZIBs), particularly under wide temperatures conditions. This study proposes a novel hydrated deep eutectic solvent based electrolyte by using ethylene glycol (EG) SnI 4 , enabling AZIBs to achieve excellent cycling life from −30 60 °C. Spectroscopic characterizations reveal H 2 O molecules effectively confined within network due dual effects Zn 2+ coordination EG hydrogen bonding, thereby weakening free water activity broadening electrochemical window. Furthermore, resulting dissociation‐reduction an organic‐inorganic hybridized solid interphase (SEI) layer is formed surface with zincophile gradient, this gradient SEI inhibits evolution regulates oriented deposition. The Zn//Zn symmetric cell utilizing achieves remarkable stability over 7800 h at room temperature, 6000 °C, 2500 work provides insights into new approach formation mechanism anode, which demonstrates significant potential for developing high

Abstract The relentless pursuit of sustainable and safe energy storage technologies has driven a departure from conventional lithium‐based batteries toward other relevant alternatives. Among these, aqueous have emerged as promising candidate due to their inherent properties being cost‐effective, safe, environmentally friendly, scalable. However, traditional systems faced limitations stemming water's narrow electrochemical stability window (~1.23 V), severely constraining density viability in high‐demand applications. Recent advancements decoupling offer novel solution overcome this challenge by separating the anolyte catholyte, thereby expanding theoretical operational voltage over 3 V. One key component innovative system is ion‐selective membrane (ISM), acting barrier prevent undesired crossover between electrolytes. This review provides comprehensive overview recent batteries, emphasizing application various types ISMs. Moreover, we summarize different specially designed ISMs performance attributes. By addressing current challenges face, outlines potential pathways for future enhancement development batteries. image
