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.

Claim (Index 55):
An electric double layer capacitor (EDLC) device comprising:\n a) a positive electrode and a negative electrode, wherein each of the positive and negative electrode comprises activated carbon and polytetrafluoroethylene; b) an inert porous separator comprising polypropylene, polyethylene or both; c) a first and a second current collector each comprising a non-corrosive metal; and d) an electrolyte comprising substantially equal volumes of propylene carbonate and dimethylcarbonate and further comprising about 1.0 M tetraethylammonium-tetrafluorob orate; wherein the positive and negative electrodes are separated by the porous separator and each is in contact with one current collector, and wherein the activated carbon comprises: a surface area of greater than 1500 m 2 /g, as determined by nitrogen sorption at 77 K and BET analysis; a pore structure comprising mesopores having a diameter ranging from 2.0 nm to 10.0 nm and a pore volume ranging from 0.01 cc/g to 0.25 cc/g for pores having a pore diameter of 0.6 nm to 1.0 nm, as determined from N 2  sorption derived DFT; and wherein each of the positive and negative electrodes independently has a specific capacitance of at least 100 F/g and a specific power of at least 25 W/g, as measured in the EDLC device.
