摘要

A graphite material for a negative electrode of a lithium-ion secondary battery is provided. A ratio Lc(112)/Lc(006) defined as a ratio of expansion of graphene sheets to sheet displacement ranges from 0.08 to 0.11, both inclusive. A crystallite size Lc(006) calculated from a wide-angle X-ray diffraction line ranges from 30 nm to 40 nm, both inclusive. An average particle size ranges from 3 μm to 20 μm, both inclusive.
