Anode for lithium secondary battery and lithium secondary battery including the same

Abstract

Provided is an anode for a lithium secondary battery of the present disclosure, comprising: an anode current collector; a first anode mixture layer formed on at least one surface of the anode current collector and including a first silicon-based active material doped with a first metal and a first conductive material; and a second anode mixture layer formed on the first anode mixture layer and including a second silicon-based active material doped with a second metal and a second conductive material, and the first conductive material has a Raman R value according to the following formula 1 that is greater than that of the second conductive material. Raman R=ID/IG  [Formula 1] (In formula 1, ID is a Raman peak intensity value in an absorption region of 1330 to 1380 cm−1, and IG is a Raman peak intensity value in an absorption region of 1550 to 1625 cm−1.)

Dependencies are inferred from the claim text.
