The invention relates to expanded graphite which is produced of a graphitic or partially graphitic starting material selected from the group consisting of natural graphite, compressed expanded graphite, partially oxidized graphite and/or graphite fibers with a BET surface of > 30 m /g, obtained by reacting the starting material with intercalatable materials, intercalatable material mixtures to a compound which is referred to as an intercalation compound and subsequently expanding it in a plasma.
