In this study, nanocarbons obtained from resorcinol–formaldehyde nanopolymers were used for polarized electrodes instead of conventionally used activated carbon in order to improve the capacitance of Electric Double Layer Capacitors (EDLCs). N2 adsorption-desorption isotherm as well as TEM observation revealed that nanocarbons used in this study has different type of pore structures compared to activated carbon. The capacitances of prepared EDLCs were evaluated from discharge characteristics. It was found that the nanocarbons containing EDLCs showed fairly high capacitance compared to activated carbon-based EDLCs. Especially, nanocarbons which have 2378 m2/g of ratio of surface area containing EDLCs showed the highest capacitance among the prepared samples. The specific capacitance of the best one was evaluated as 215 F/g. It was also found that the nanocarbons obtained from resorcinol–formaldehyde nanopolymers containing EDLCs plays an essential role in the improvement of capacitance.
