Abstract

See full text

Disclosed is a negative electrode active material which includes: a silicon oxide composite including i) Si, ii) a silicon oxide represented by SiOx (02SiO4 and MgSiO3 at the same time and shows no peak of MgO; the ratio of peak intensity, I (Mg2SiO4)/I (MgSiO3), which is intensity I (Mg2SiO4) of peaks that belong to Mg2SiO4 to intensity I (MgSiO3) of peaks that belong to MgSiO3 is smaller than 1, the peaks that belong to Mg2SiO4 are observed at 2θ=32.2±0.2°, and the peaks that belong to MgSiO3 are observed at 2θ=30.9±0.2°.
