RAW MATERIAL CARBON COMPOSITION FOR NEGATIVE ELECTRODE MATERIAL OF LITHIUM-ION SECONDARY BATTERY |
摘要 |
Provided is a raw material carbon composition for a negative electrode material for a lithium-ion secondary battery useful for achieving excellent high-speed charge and discharge characteristics. The raw material carbon composition is obtained by subjecting a stock oil composition to coking treatment, the stock oil composition being obtained by blending a stock oil (1) having a density at 15° C. of from 0.96 to 1.05 g/cm3 and an aromatic carbon fraction (fa) of from 0.40 to 0.65 with a stock oil (2) having a saturated component of from 40 to 80% by weight detectable by development by using thin-layer chromatography, in such an amount that a ratio of the stock oil (1) to the sum of the stock oils (1) and (2) becomes 55 to 80% by volume.
