Abstract
There is disclosed a carbon material from which an electric double layer capacitor (EDLC) having a large capacitance can be fabricated. First, a carbon material is activated to produce crystallites of graphite-like carbon having interlayer distances of 0.365 to 0.385 nm. Positive and negative plates are fabricated using the crystallites.
