摘要:
The invention provides a stock oil composition for a carbon material for a negative electrode for a lithium ion secondary battery, having a 10 vol % distillation temperature of 280° C. or higher as the distillation property, a density of at least 0.90 g/cm3 at a temperature of 15° C. and a normal paraffin content of at least 3 parts by weight with respect to 100 parts by weight as the total weight of the stock oil composition; and having an aromatic component content of 30-85 parts by weight with respect to 100 parts by weight as the total weight of the stock oil composition and an aromatic component molecular weight of 250-1600 when the aromatic components and non-aromatic components are separated by elution chromatography.
