More Information
Summary:An anode for a lithium secondary battery includes an anode current collector, a first anode active material layer formed on at least one surface of the anode current collector and including a silicon-based active material and a graphite-based active material, and a second anode active material layer formed on the first anode active material layer and including a porous structure as an active material. The porous structure includes carbon-based particles including pores, and a silicon-containing coating formed at an inside of the pores of the carbon-based particles or on the surface of the carbon-based particles.
