Negative electrode material for lithium ion secondary battery, negative electrode for lithium ion secondary battery, and lithium ion secondary battery

Abstract

A negative electrode material for a lithium ion secondary battery includes particles in a state in which a plurality of flat graphite particles are aggregated or bonded, and in the negative electrode material, with respect to a volume-based particle diameter measured by a laser diffraction/scattering method, a cumulative value at 9.516 μm is 8.0% or less, a standard deviation of a particle size distribution is 0.22 or less, and a specific surface area is 3.0 m2/g or less.
