Abstract
Provided is a stock oil composition for a carbonaceous material for a negative electrode of a lithium-ion secondary battery which composition is useful for achieving excellent high-speed charge and discharge characteristics. The stock oil composition for a carbonaceous material for a negative electrode of a lithium-ion secondary battery uses a bottom oil of residue fluid catalytic cracking apparatus as a raw material. The stock oil composition comprises, of a saturated component, an aromatic component, a resin component and an asphaltene component detectable by development of the stock oil composition using thin-layer chromatography, the saturated component ranging from 30 to 50% by weight and the aromatic component ranging from 50 to 70% by weight; and has an average molecular weight of from 400 to 600.
