More Information
Summary:An anode active material for a secondary battery according to an embodiment of the disclosed technology includes an anode current collector, a first anode active material layer on at least one surface of the anode current collector and including a graphite-based active material and a silicon-based active material doped with a metal element, and a second anode active material layer on the first anode active material layer and including a porous structure. The porous structure includes a carbon-based particle having pores and a silicon-containing coating formed inside the pores or on a surface of the carbon-based particle.
