Abstract

See full text

Provided are a negative electrode active material which includes negative electrode active material particles which includes a silicon oxide (SiOx, 02SiO3, Li2Si2O5, and Li4SiO4 in at least a part of the silicon oxide. The negative electrode active material particles have a maximum peak position by a Raman spectrum of more than 460 cm−1 and less than 500 cm−1. Also provided are a method of preparing the same, and a negative electrode and a lithium secondary battery including the negative electrode active material.
