摘要： To provide a negative electrode carbon material capable of suppressing capacity degradation which will occur due to repetition of a charge/discharge cycle, storage under a charged state, float charging, or the like. An artificial graphite for a negative electrode of a lithium secondary battery having a c-axis crystallite size L (112) of from 2.0 to 4.2 nm as calculated from a (112) diffraction line obtained by X-ray wide-angle diffractometry and having a half-value width ΔνG of from 15 to 19 cm−1 for a peak appearing in a wavelength region of from 1580 cm−1±100 cm−1 in the Raman spectroscopy using an argon ion laser light having a wavelength of 5145 angstrom.

摘要： The present invention provides a raw coke having such a structure that the graphitized product resulting from graphitization of the raw coke at a temperature of 2800° C. under an inactive gas atmosphere will have ratios of the crystallite size to the lattice constant of 360 or less in the (002) plane and 1500 or less in the (110) plane, as a raw coke providing active carbon produced by alkali-activating the raw coke, which is reduced in remaining alkali content and can simplify washing operation because washing liquid can easily pass through the activated carbon, or as a raw coke for the production of needle coke.
