ABSTRACT:
The invention is directed to a carbon composition produced from a carbon precursor, a carbon precursor modifier, and an additive, wherein a mixture of the recited components is formed, the carbon precursor is cured, the resulting mixture carbonized to produce a porous carbon composition. Also disclosed are methods for preparing the carbon composition and for using the carbon composition to fabricate electrodes and electric double layer capacitors comprising the carbon composition.
