与你共享!Carbon-Based Supercapacitors Produced by Activation of Graphene

Supercapacitors, also called ultracapacitors or electrochemical capacitors, store electrical charge on
high-surface-area conducting materials. Their widespread use is limited by their low energy storage
density and relatively high effective series resistance. Using chemical activation of exfoliated
graphite oxide, we synthesized a porous carbon with a Brunauer-Emmett-Teller surface area of up
to 3100 square meters per gram, a high electrical conductivity, and a low oxygen and hydrogen
content. This sp2-bonded carbon has a continuous three-dimensional network of highly curved,
atom-thick walls that form primarily 0.6- to 5-nanometer-width pores. Two-electrode
supercapacitor cells constructed with this carbon yielded high values of gravimetric capacitance
and energy density with organic and ionic liquid electrolytes. The processes used to make this
carbon are readily scalable to industrial levels.
