Porous activated glucose-derived carbon materials (samples AGC-600-x) are fabricated with a facile impregnation-calcination strategy by using zinc chloride (ZnCl2) as a chemical etchant. The analytic results reveal that the representative sample AGC-600-2 possesses a porous structure with high surface area (S-BET = 1690 m(2) g(-1)). When used as electrode materials, the sample AGC-600-2 exhibits a specific capacitance of 176.75 F g(-1)at 1.0 A g(-1) in a three-electrode system. Moreover, AGC-600-2-based symmetrical supercapacitor possesses an energy density of 17.99 Wh kg(-1) at the power density of 399.94 W kg(-1). Also, the as-prepared symmetrical two-electrode supercapacitor displays superior recyclability, with only 8.1% capacitance loss after 10000 chargedischarge cycles at 1.0 A g(-1). The strategy adopted in this work offers a facile way to fabricate the porous glucose-derived carbon materials at a large scale, which is crucial for their practical applications in supercapacitors, batteries and filters.
