<P>PROBLEM TO BE SOLVED: To provide a carbonaceous material with reduced unevenness in the state in which the graphene sheets face each other. <P>SOLUTION: The carbonaceous material includes a stack of graphene sheets and a substance intercalated between the graphene sheets, and is expanded graphite that gives an XRD pattern which includes diffraction peaks respectively in the 2θ ranges of 7 to 12° and 18 to 24° and in which a diffraction peak appearing in the range of 25 to 27° has a lower height than the diffraction peak appearing in the range of 18 to 24°, and the peak which appears in the 2θ range of 7 to 12° has a half-value width of 4° or less. <P>COPYRIGHT: (C)2013,JPO&INPIT |
