Monolithic electrode for electric double-layer capacitors based on macro/meso/microporous S-Containing activated carbon with high surface area

Macro/meso/microporous carbon monoliths doped with sulfur have been prepared from sulfonated poly(divinylbenzene) networks followed by the activation with CO_2 resulted in the activated carbon monoliths with high surface area of 2400 m^2 g^[−1]. The monolithic electrode of the activated carbon shows remarkably high specific capacitance (175 F g^[−1] at 5 mV_s^[−1] and 206F_g^[−1] at 0.5 Ag^[−1])
