| description | The present invention relates a negative electrode for a lithium secondary battery, and a lithium secondary battery comprising same, wherein the negative electrode for a lithium secondary battery comprises a current collector, and a negative electrode active material layer including a first layer formed on the current collector and a second layer formed on the first layer, the first layer containing a first carbon-based negative electrode active material, and the second layer containing a second carbon-based negative electrode active material, wherein the degree of divergence (DD) value of the first layer is 30-90% of the DD value of the negative electrode active material layer, the DD value is defined by formula 1 below. DDDegreeofDivergence=Ia/Itotal*100(In formula 1, Ia is the sum of peak intensities of peaks at out-of plane angles as measured by XRD with CuKα, and Itotal is the sum of peak intensities of peaks at all angles as measured by XRD with CuKa). |
