Abstract
A negative electrode and a lithium secondary battery including the same. The negative electrode includes a current collector; and a negative electrode active material layer on at least one surface of the current collector. The negative electrode active material layer includes 1) a negative electrode active material including a Mg-containing silicon oxide, a carbon coating layer surrounding the surface of the Mg-containing silicon oxide and a graphene coating layer surrounding the surface of the carbon coating layer, 2) a conductive material including single-walled carbon nanotubes (SWCNTs), and 3) a binder. The graphene has a D/G band intensity ratio of 0.8 to 1.5. The D/G band intensity ratio is defined as an average value of the ratio of the maximum peak intensity of D band at 1360 ± 50 cm-1 based on the maximum peak intensity of G band at 1580 ± 50 cm-1, as determined by Raman spectroscopy of graphene.
