Supercapacitors, also called ultracapacitors or electrochem. capacitors, store elec. charge on high-surface-area conducting materials. Their widespread use is limited by their low energy storage d. and relatively high effective series resistance. Using chem. activation of exfoliated graphite oxide, the authors synthesized a porous C with a BET surface area of up to 3100 m2/g, a high elec. cond., and a low O and H content. This sp2-bonded C has a continuous 3-dimensional network of highly curved, atom-thick walls that form primarily 0.6-5 nm wide pores. Two-electrode supercapacitor cells constructed with this C yielded high values of gravimetric capacitance and energy d. with org. and ionic liq. electrolytes. The processes used to make this C are readily scalable to industrial levels. [on SciFinder(R)]
