Abstract:
A carbon prepared according to the following steps:polymerizing a polymerizable component from a mixture containing said polymerizable component and a surfactant so as to form a polymer, said surfactant and said polymerizable component being present in said mixture in a molar ratio of at least 0.2:1 and said polymer having an average pore size greater than 4 nm, and a density greater than 0.1 g/cc; carbonizing the polymer; activating the carbon; and wherein said carbon is an activated carbon and has a volumetric capacitance in a non-aqueous electrolyte of at least 20 F/cc, a pore size greater than 2 nm, a density greater than 0.1 g/cc, a surface area between 200 and 2,000 m2/g, and an electrical conductivity greater than 10 Scmâˆ’1.
