Abstract Proton batteries are promising candidates for next‐generation large‐scale energy storage in extreme conditions due to the small ionic radius and efficient transport of protons. Hydrogen gas, with its low working potentials, fast kinetics, stability, further enhances performance proton but necessitates development novel electrolytes freezing points reduced corrosion. This work introduces a localized water restriction strategy by incorporating tertiary component high donor number, which forms strong bonds molecules. approach restricts free molecules reduces average hydrogen bond ratio strength. As‐prepared ternary eutectic lowered point −103 °C, significantly lower than traditional binary electrolyte (9.5 m H 3 PO 4 , −93 °C). is highly compatible Cu 0.79 Co 0.21 [Fe(CN) 6 ] 0.64 ⋅ 4H 2 O (CoCuHCF) cathode, reducing material dissolution current collector The ||CoCuHCF battery using this demonstrated high‐power density 23664.3 W kg −1 excellent at −80 stable cyclability over 1000 cycles (>30 days) −50 °C. These findings provide framework electrolytes, highlighting potential challenging environments.
