Abstract
A method of producing a graphite intercalation compound by intercalating a substance into graphite between layers thereof, characterized in that graphite particles are subjected to electrolysis in an electrolytic solution containing a substance capable of intruding into the interlayer spacings of the graphite while applying a load to the graphite particles in at least one direction to press all the graphite particles to the surface of an anode. According to the method, there can be obtained the desired porduct having a uniform and high quality.
Claims6
A method of producing a graphite intercalation compound in an electrolytic cell having a cathode, an anode and an andoe chamber adapted to accommodate graphite particles therein, which comprises electrolyzing graphite particles in the anode chamber in an aqueous electrolytic solution containing a substance capable of intruding into the interlayer spacings of graphite, thereby intercalating said substance into the interlayer spacings of graphite, wherein the electrolyzing is carried out at a current density of less than 500 mA.sup.2 /cm.sup.2 and while applying a pressure to the graphite particles accommodated in the anode chamber in at least one direction so as to press the graphite particles against the surface of the anode.
