RAW MATERIAL CHARCOAL COMPOSITION FOR NEGATIVE ELECTRODE MATERIAL OF LITHIUM ION SECONDARY BATTERY AND METHOD FOR PRODUCING THE SAME |
摘要 |
In the raw coke composition of the invention, as the starting material for a negative electrode material of a lithium ion secondary battery, the ratio of the crystallite size Lc(002) and lattice constant co(002) (Lc(002)/co(002)) on the 002 face is no greater than 180, and the ratio of the crystallite size La(110) and the lattice constant ao(110) (La(110)/ao(110)) on the 110 face is no greater than 1500, as determined by X-ray diffraction upon graphitizing in an inert gas atmosphere at a temperature of 2800°C. |
