Abstract:
The present disclosure relates to an anode for a lithium secondary battery and a lithium secondary battery including the same, wherein the anode includes a first anode active material layer formed on at least one surface of the anode current collector, wherein the first anode active material layer contains a mixture of natural graphite and artificial graphite as the anode active material and a first binder; a second anode active material layer formed on the first anode active material layer, wherein the second anode active material layer contains a mixture of artificial graphite and a silicon-based compound as the anode active material and a second binder; and wherein a weight ratio of the first binder and the second binder is 1 to 2:1.
