Abstract
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,
