... Carbide formation in the graphite intercalation compound with lithium, LiC 12 . Abstract A second stage graphite intercalation compound LiC 12 was synthesized using lithium foil and highly oriented pyrolytic graphite. ... It was shown that composite obtained consists of at least two carbide phases: thermodynamically stable Li 2 C 2 and some metastable carbide phase which, perhaps, is stabilized by graphite matrix. ...
