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.

L'invention se rapporte aux dispositifs capacitifs à double couche électrique (EDLC). Dans un aspect, la présente invention concerne une électrode comprenant un cryogel à charbon actif possédant une structure de pores ajustable dans laquelle : la superficie est d'au moins 1500 m2/g tel que définie par la sorption d'azote à 77K et l'analyse BET ; et la structure des pores comprend un volume de pores allant d'environ 0,01 cm3/g à environ 0,25 cm3/g pour les pores ayant un diamètre de 0,6 à 1,0 nm. Selon un autre aspect, la présente invention concerne un dispositif à condensateur à double couche électrique (EDLC) comprenant un cryogel actif.
