NEGATIVE ELECTRODE MATERIAL FOR LITHIUM ION SECONDARY BATTERY, NEGATIVE ELECTRODE FOR LITHIUM ION SECONDARY BATTERY, AND LITHIUM ION SECONDARY BATTERY

A negative electrode active material for a lithium ion secondary battery includes graphite particles for which an R value measured by Raman spectrometry is less than 0.27, and an intensity ratio (P1/P2) of a diffraction peak (P1) on a hexagonal structure (101) plane to a diffraction peak (P2) on a rhombohedral structure (101) plane in an X-ray diffraction pattern by CuKα ray is 5.0 or less.
