  • Publication number: 20240274800
    Abstract: An anode for a secondary battery is disclosed. In some implementations, the anode 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 including a carbon coating layer formed on a surface thereof, 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. The first conductive material has a Raman R value, greater than or equal to a Raman R value of the second conductive material. According to some implementations, volume expansion/contraction of a silicon-based active material may be alleviated during battery charging/discharging.
