Abstract
A negative electrode material for a lithium ion battery according to an embodiment of the present disclosure includes graphite particles and amorphous carbon particles. The graphite particles have a median diameter (D50) A of 8.0 μm or more and 11.0 μm or less. A ratio A/B of the median diameter A (μm) to a median diameter (D50) B (μm) of the amorphous carbon particles satisfies a relation of 1.1<(A/B)≤2.75.
