An expanded graphite is derived from 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 having a BET surface area of >30 m2/g. The expanded graphite is obtained by reaction of the starting material with substances capable of intercalation or mixtures of substances capable of intercalation to give a compound designated as an intercalation compound and subsequent expansion in plasma.
