An anode for a lithium secondary battery includes an anode current collector, and an anode active material layer formed on at least one surface of the anode current collector. The anode active material layer includes an anode active material and an anode binder. The anode active material includes a plurality of composite particles, each of the composite particles include a silicon-based active material particle, and a solid electrolyte interphase (SEI) layer formed on at least a portion of a surface of the silicon-based active material particle. A relative standard deviation of thickness values of the SEI layer of the composite particles, which are measured by an X-ray photoelectron spectroscopy (XPS) from 9 different composite particles among the plurality of composite particles after repeating 100 cycles of charging and discharging is 20% or less.
