Abstract:
Disclosed are a negative electrode for a rechargeable battery and a rechargeable battery including the same. The negative electrode for a rechargeable battery according to an exemplary embodiment of the present invention includes a substrate and an active material layer including graphite formed on at least one surface of the substrate, wherein the active material layer includes an internal layer relatively adjacent to the substrate and a surface layer relatively away from the substrate and the internal layer and the surface layer have a degree of divergence (DD) defined by Equation 1 below, and the DD value of the surface layer is 6% to 50% of the DD value of the internal layer. DD(Degree of Divergence)=(Ia/Itotal)×100  [Equation 1](Ia is a sum value of peak intensities appearing at a non-planar angle when XRD is measured using a CuKα line, and Itotal is a sum value of peak intensities appearing at every angle when XRD is measured using the CuKα line).
