Patent abstract
The present application is directed to electric double layer capacitance (EDLC) devices. In one aspect, the present application is directed to an electrode comprising an activated carbon cryogel having a tunable pore structure wherein: the surface area is at least 1500 m2/g as determined by nitrogen sorption at 77K and BET analysis; and the pore structure comprises a pore volume ranging from about 0.01 cc/g to about 0.25 cc/g for pores having a pore diameter of 0.6 to 1.0 nm. In another aspect, the present application is directed to an Electric Double Layer Capacitor (EDLC) device comprising an activated cryogel.
