초록 ▼

An active carbon suitable for use in electrodes for an organic solvent type electric double layer capacitor, which is obtained by calcining an easily graphitizable organic substance and then activating the resultant carbonized product with an alkali, wherein a mode in the pore size distribution of the active carbon according to a transmission electron microscope (TEM) image analysis method falls within a range of 10-20 angstroms, and an conjunctive pore rate, which is expressed by a proportion of the total area of pores having an area not smaller than 500 square angstroms to the whole pore area in the TEM image, is at least 20%.

대표청구항 ▼

[ What is claimed is:] [1.] An active carbon suitable for use in electrodes for an organic solvent type electric double layer capacitor, which is obtained by calcining an easily graphitizable organic substance to produce a carbonized product and then activating the carbonized product with an alkali, wherein the active carbon has pores having a pore size distribution wherein a mode in the pore size distribution according to a transmission electron microscope (TEM) image analysis method falls within a range of 10-20 angstroms, and a conjunctive pore rate, which is expressed by a proportion of a total area of pores having an area not smaller than 500 square angstroms to a whole pore area in the TEM image, is at least 20%.
