Abstract Rechargeable aqueous zinc batteries (AZBs) utilizing water‐borne electrolytes are intrinsically safe electrochemical devices that promising in next‐generation energy storage. Such application requires adaptivity to global climate, especially at grid‐scale, thus their stability of performance varying temperatures is critical. Many essential properties AZBs, i.e., ion transfer, redox kinetics, etc., largely governed by the because relatively limited stable phase temperature water. This limitation extremely vital cold regions since charging and discharging become more difficult sub‐zero range due water freezing. Despite development various electrolyte strategies recent years, comprehensive reviews focusing on this topic remain limited. research diverse reasons underneath failure AZBs extreme provides a thorough analysis possible resolutions from an perspective. It starts with challenges faced both high low concerning electrolytes. Different addressing these discussed, providing insights into under conditions. Finally, review concludes summary outlook design structure for all‐weather integrating innovative non‐aqueous battery systems.

Abstract Sodium metal batteries (SMBs) offer a promising alternative to lithium‐ion systems due the natural abundance of sodium. Nevertheless, their practical application is hindered by challenges sodium dendrite growth and unstable electrolyte/electrode interfaces in conventional liquid electrolytes. Here, an situ polymerized localized high‐concentration gel electrolyte (IS‐LHCE) presented engineered through strategic integration 1,3‐dioxolane as both diluent polymer precursor. Unlike approaches using inert diluents, design establishes polymer‐confined solvation structure that simultaneously achieves anion coordination regulation ion transport decoupling. This unique configuration reduces Na + activation energy 0.0379 eV, enabling exceptional ionic conductivity 6.07 × 10 −4 S cm −1 wide electrochemical stability window (≈4.56 V). The formed network IS‐LHCE promotes preferential decomposition, forming gradient inorganic‐rich solid interphase dominated NaF/Na 2 phases, which enables Na||Na symmetric achieve unprecedented cycling over 1,200 h at 0.1 mA −2 . 3 V (PO 4 ) ||Na full demonstrate record‐breaking longevity, with 90.8% capacity retention after 3,000 cycles C rate. work presents new paradigm design, fundamentally resolving longstanding trade‐offs between interfacial instability transport, avoiding formation, advances high‐energy‐density SMBs.
