<p>Disclosed are: a carbon material for an electric double layer capacitor, which is capable of providing large capacity by high-voltage charging; a method for producing the carbon material; and an electric double layer capacitor using the carbon material. Also disclosed are: a carbon material for an electric double layer capacitor, which is capable of improving the electric double layer capacity in high-voltage charging; a method for producing the carbon material; and an electric double layer capacitor using the carbon material. Specifically disclosed is a carbon material for an electric double layer capacitor, which is characterized in that: the interplanar spacing (d002) of carbon hexagonal network planes as determined by X-ray diffraction is 0.355-0.370 nm; the crystallite size (Lc) of the network planes in the lamination direction is 1-2 nm; and the electrode bulk density is 0.8-0.9 g/cm3. Also specifically disclosed is an electric double layer capacitor comprising a polarizable electrode immersed in an electrolyte solution, which is characterized in that the polarizable electrode is formed using the above-described carbon material.</p> |
