A new type of supercapacitor electrode is reported, prepared by pressing a carbon nanotube/polyacrylonitrile blend and then pyrolyzing the pellet (see Figure). Although their specific surface area is very low, e.g., 200 m 2 g –1 , the C/C composites demonstrate high values of capacitance, up to 100 F g –1 . The authors propose two explanations for these remarkable values.
