摘要： An anode for a secondary battery includes an anode current collector, a first anode mixture layer on at least one surface of the anode current collector, and a second anode mixture layer on the first anode mixture layer. The first anode mixture layer includes a first silicon-based active material having a carbon coating layer formed on a surface, and a first conductive material, the second anode mixture layer includes a second silicon-based active material doped with a metal, and a second conductive material, and the anode for a secondary battery exhibits a Radial Breathing Mode (RBM) peak in a Raman spectrum obtained from a surface of the second anode mixture layer. An influence of volume expansion/contraction of a silicon-based active material during battery charging/discharging may be alleviated.
