Carbide formation in the
graphite intercalation compound with lithium, LiC12
Abstract
A second stage graphite
intercalation compound LiC12 was synthesized using lithium foil and highly
oriented pyrolytic graphite. LiC12 was characterized by XRD, DSC and 7Li NMR
spectroscopy. Carbide formation inside LiC12 was
performed at 1173 K for an hour. It was shown that composite obtained consists
of at least two carbide phases: thermodynamically stable Li2C2 and some
metastable carbide phase which, perhaps, is stabilized by graphite matrix. The
product obtained after water treatment of the composite is to be graphite–like
materials with enriched defectiveness.
