PROBLEM TO BE SOLVED: To provide a method of manufacturing carbon composite fine particles which contain natural graphite having random orientation and high crystallinity and have improved adhesive properties to a pole plate of the natural graphite and are suitable for a negative electrode material in a lithium ion secondary battery. SOLUTION: The method of manufacturing the carbon composite fine particles comprises heating a kneaded material obtained by kneading (1) natural graphite, (2) at least one kind of a spherical carbon component selected from a spherical carbon precursor and a spherical carbon material and (3) a binder at 2,400 to 3,000 deg.C, if necessary after it is subjected to the primary heating at 700 to 1,500 deg.C. |
