The ammonium-ion supercapacitor (AISC) with nonmetal charge carriers exhibits merits of element abundance and compatibility aqueous electrolytes. However, it still suffers from severe performance degradation at low temperatures. Herein, a novel deep eutectic solvent (DES) containing H2O, ethylene glycol, (NH4)2SO4 is designed shows freezing point −46.3 °C. DES further incorporated in poly(vinyl alcohol)/gelatin gels to prepare eutectogel that demonstrates favorable mechanical flexibility high ionic conductivity 45.6 mS cm–1 room temperature. Furthermore, the also an excellent self-extinguishing property. AISC consisting optimized carbon electrodes indicates remarkable cycling stability ∼100% capacitance retention Coulombic efficiency after 30 000 charge–discharge cycles. Moreover, flexible electrochemical under harsh conditions, such as bending deformation, damaged state, low-temperature environments. Therefore, this work provides innovative promising platform for next-generation energy storage systems.
