Ultramicroporous carbon as electrode material for supercapacitors

Abstract. Poly(vinylidene fluoride)-derived ultramicroporous carbon with a specific surface area of 1012 m2 g
-1 and a very narrow pore-size distribution peaked at 0.55 nm is investigated as electrode material for supercapacitors. The unique microstructure features enable the carbon to present not only a high gravimetric capacitance (264 F g
-1) but also a high electrode density (0.826 g cm…
