摘要:
An anode for a lithium secondary battery includes an anode current collector, a second anode active material layer disposed on the anode current collector and including a second anode active material that includes a graphite-based active material and composite particles, and a first anode active material layer disposed between the anode current collector and the second anode active material layer and including a first anode active material that includes a graphite-based active material and does not include the composite particles. Each of the composite particles includes a carbon-based particle including pores, a silicon-containing coating layer disposed on an inside of the pores of the carbon-based particle or on a surface of the carbon-based particle, and a surface oxide layer disposed on the silicon-containing coating layer and including a silicon oxide.
