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.
