Claim:
1. A method of preparing a carbide-derived carbon, comprising: thermally treating a carbide compound in a vacuum, thus obtaining a vacuum-treated carbide compound wherein lattice spacing of the vacuum-treated carbide compound is increased; and thermochemically reacting the vacuum-treated carbide compound with a halogen element-containing gas, thus extracting an element other than carbon from the vacuum-treated carbide compound, wherein the carbine-derived carbon has an XRD (X-ray diffraction) peak intensity of 6000 to 8000 between 20° and 30°; and; wherein thermally treating in a vacuum is performed at 1100˜1900° C. for 3˜7 hr.
