Document Type and Number:

Japanese Patent JP6160770

Kind Code:

B2

Abstract:

A negative electrode material for a lithium-ion secondary battery, in which the negative electrode material includes a composite particle including a spherical graphite particle and plural graphite particles that have a compressed shape and that aggregate or are combined so as to have nonparallel orientation planes, and the negative electrode material has an R-value in a Raman measurement of from 0.03 to 0.10, and has a pore volume as obtained by mercury porosimetry of from 0.2 mL/g to 1.0 mL/g in a pore diameter range of from 0.1 µm to 8 µm.
