▎ 摘　　要

NOVELTY - Flake graphite comprises graphene or laminate of graphene sheets, when the Raman spectrum of the flaky graphite is measured by Raman spectroscopy, the ratio 2D/G being peak area ratio between the 2D band and G band of a Raman spectrum is 0.5-5, and when the Raman spectrum of the flake graphite is measured using Raman spectroscopy, the halogen content ratio in the flake graphite is no more than 1000 ppm. USE - The flake graphite is used in electrode material. ADVANTAGE - The flake graphite does not readily fold in or curl and does not readily corrode an electrode when used in an electrode material, enhances gas barrier property, flame retardancy, conductivity, handleability and thermal conductivity, improves physical properties such as the mechanical strength of the resin, and does not harden to corrode an electrode. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for producing the flaky graphite involving preparing graphite intercalation compound in which at least an alkali metal is intercalated between graphene layers of graphite, and exfoliating the graphite to obtain flaky graphite by mixing the graphite intercalation compound and compound having carbonyl group is provided.
