Abstract

An anode for a lithium secondary battery according to an embodiment of the present disclosure includes: an anode current collector; a first anode mixture layer which is formed on at least one surface of the anode current collector and includes a first carbon-based active material; and a second anode mixture layer which is formed on the first anode mixture layer and includes a second carbon-based active material and a silicon-based active material, wherein the first anode mixture layer has a Raman R value according to the following Equation 1, which is smaller than that of the Raman R = I D / I G <img class="EMIRef" id="03096f05-6fec-4008-92d8-a2a410a85dd1-ia01" /> second anode mixture layer: Raman R = I<D> / I<G> wherein I<D> is a peak intensity value in an absorption region of 1350 to 1380 cm<-1>, and I<G> is a peak intensity value in the absorption region of 1580 to 1600 cm<-1>.
