Abstract:
A negative electrode active material including: a particle of negative electrode active material containing silicon-based material of SiO x  (0.5≤x≤1.6); wherein the intensity A of a peak in a Si-region given in the chemical shift region of from −50 to −95 ppm and the intensity B of a peak in a SiO 2 -region given in the chemical shift region of from −96 to −150 ppm in a  29 Si-MAS-NMR spectrum of the silicon-based material satisfy a relationship that A/B≥0.8. This provides a negative electrode active material which can increase a battery capacity, and can improve cycle characteristics and initial charge/discharge characteristics when used as a negative electrode active material for a lithium ion secondary battery.

Claim (Index 7):
The negative electrode active material according to  claim 5 , wherein the Li 2 SiO 3  has a diffraction peak near 38.2680\u00b0 in which the full width at half maximum (2\u03b8) is 0.75\u00b0 or more in an X-ray diffraction.
