a N2 adsorption–desorption isotherms of hyperporous carbons and HCP-Ben at 77 K. b NLDFT pore distributions of hyperporous carbons and HCP-Ben. c BET surface areas with contributions from micropores and mesopores of hyperporous carbons and HCP-Ben. Error bars are standard deviations for BET surface areas. d Specific capacitances of hyperporous carbons at different scan rates calculated from CV curves using three-electrode cells at 20 °C. The mass loading of the working electrode is 0.7 mg/cm2.
