Crystalline carbonaceous material with controlled interlayer spacing and method of preparing same

A crystalline carbon material with controlled interlayer spacing and a method of manufacturing the crystalline carbon material are disclosed. The crystalline carbon material has peaks of a (002) plane at 2¸=23°±5.0° and 2¸=26.5°±1.0° when X-ray diffraction is measured using a CuK± ray. The peak height at 2¸=23°±5.0° is higher than the one at 2¸=26.5°±1.0°.
