摘要

The raw cobalt composition according to the present invention is a raw material for a cathode material for a lithium ion secondary battery. When the graphite is subjected to graphitization at a temperature of 2800 캜 under an inert gas atmosphere, the crystallite size Lc (002) / co (002) of the lattice constant co (002) to the lattice constant co (002) is 180 or less and the ratio of the crystallite size La (110) / ao (110)) is 1500 or less.
