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
-3), resulting in an
outstanding high volumetric capacitance of 218 F cm-
3 in 6 mol L
-1 KOH aqueous electrolytes. However,
the carbon shows a very small capacitance of less than 7 F g
-1 in 1 mol L-
1 Et4NBF4/PC, which implies the
pores are too small to be accessible even for the desolvated ions in the non-aqueous electrolyte.
