Zusammenfassung:The present invention relates an anode for a lithium secondary battery and a lithium secondary battery comprising same. The anode for a lithium secondary battery comprises a current collector; and an anode active material layer formed on the current collector and including a carbon-based anode active material, wherein the anode active material layer has a multi-layer structure of three or more layers and at least one layer of the anode active material layer is an oriented layer having a degree of divergence (DD) of 19 or greater, the DD being defined by the following formula 1:Degree of Divergence (DD)=(Ia/Itotal)*100  [formula 1](In formula 1,Ia is a sum of peak intensities at non-planar angles measured by XRD using a CuKα ray, and,Itotal is a sum of peak intensities at all angles measured by XRD using a CuKα ray).
