A porous carbon characterized by a volumetric pore size distribution having two peaks, a first of said peaks being between 0.5 and 1.0 nm and a second of said peaks being between 1.0 and 5.0 nm. The porous carbon may have a volumetric capacitance in an organic electrolyte of at least 40 F/cm3, an average pore diameter between about 2 nm and about 30 nm, a surface area of at least 900 m2/g, and/or a density of at least 0.4 g/cm3. A method for making such a carbon includes a) curing a mixture comprising a carbohydrate, a dehydrating component, and a nonmetallic cationic pore-forming agent and b) carbonizing the cured carbon under conditions effective to provide a porous carbon having a surface area between about 100 m2/g and about 3000 m2/g. The dehydrating component and nonmetallic cationic component may comprise two moieties of one compound.
L'invention concerne un carbone poreux caractérisé en ce qu'il a une distribution de sa taille poreuse volumétrique présentant deux pics, le premier desdits pics étant compris entre 0,5 et 1,0 nm et le second entre 1,0 et 5,0 nm. Le carbone poreux peut posséder une capacité volumétrique dans un électrolyte organique d'au moins 40 F/cm?3¿, un diamètre poreux moyen compris entre environ 2 nm et environ 30 nm, une surface active d'au moins 900 m?2¿/g, et/ou une densité d'au moins 0,4 g/cm?3¿. Un procédé d'élaboration d'un tel carbone consiste à a) durcir un mélange contenant un glucide, un composé de déshydratation et un agent de formation de pore cationique non métallique et à b) saturer le carbone durci dans des conditions efficaces de manière à produire un carbone poreux possédant une surface active allant d'environ 100 m?2¿/g à environ 3000 m?2¿/g. Ce composé de déshydratation et le composé cationique non métallique peuvent renfermer deux groupes fonctionnels d'un composé.
