Abstract The susceptibility to freezing of the electrolyte and mismatched cathode make aqueous zinc‐ion hybrid supercapacitors (ZHSCs) have inferior electrochemical performance at low temperature. Herein, a novel freeze‐tolerant hydrogel (CEEZ) matched graphene/porous carbon/cellulose nanofibers (GPCN) are respectively fabricated via chemical cross‐linking two‐step process assemble ZHSCs. prepared electrode has highly porous structure, abundant edge active sites, increased interlayer spacing, which collectively reduces ion transport complexity enhances contact area with electrolyte, promoting rapid ionic conduction pathways. For CEEZ, use ethylene glycol saturated vapor pressure water, thereby enhancing frost resistance electrolyte. Consequently, ZHSCs assembled from GPCN, Zn anode exhibit excellent specific capacitances 1.11 F cm⁻ 2 (21.35 3 ) 20 °C 0.74 (14.23 −20 °C. These results demonstrate promising application potential these in cold environments while maintaining impressive energy storage capabilities. This work provides valuable insights robust strategy for design high‐performance low‐temperature ZHSCs, their practical applicability renewable systems.
