The distribution of micropores and ultrafine pores facilitates effective connection and ion transport at the electrode–electrolyte interface, leading to an increase in the number of active sites in carbon materials and ultimately improving their specific capacitance. Nitrogen-containing groups also provided additional pseudocapacitance.
