In light of the “rich coal，poor oil，and scarce gas” resource status in China，developing carbon electrode materials from coal can accelerate the transformation of clean and efficient utilization of coal and the realization of “dual carbon” goals. Herein，the porous carbon is synthesized from Shenmu bituminous coal via a one-step KOH activation strategy. The results indicate that the resultant carbon possesses a hierarchical porous structure with a surface area of 2094.5 m²·g^-1 and pore volume of 0.96 cm³·g^-1，abundant graphitized microcrystals，N/O co-doping，and excellent hydrophilicity. By employing as-fabricated carbon as cathode，2 mol·L^-1 ZnSO₄ aqueous solution as electrolyte，and Zn foil as anode，the assembled coin-type Zn-ion hybrid supercapacitors （ZIHSCs） exhibit a high capacity of 178.7 mAh·g^-1 at 0.1 A·g^-1 and retain 89.2 mAh·g^-1 by enlarging the current density 200 times to 20 A·g^-1，manifesting an eminent rate performance. Importantly，the maximum energy density and power density of ZIHSCs can reach 142 Wh·kg^-1 and 16854.9 W·kg^-1，respectively. Furthermore，the quasi-solid ZIHSCs based on the gel electrolyte of gelatin@ZnSO₄ also deliver outstanding electrochemical capability and excellent flexibility.
