Abstract

An anode for a lithium secondary battery includes an anode current collector, and an anode active material layer on the anode current collector. The anode active material layer includes a carbon-based active material and a silicon-based additive. A content of the silicon-based additive is in a range from 0.1 wt% to 1.0 wt% based on a total solid weight of the anode active material layer. A silicon crystallite size of a (111) plane of the silicon-based additive measured by an X-ray diffraction (XRD) analysis is in a range from 100 nm to 500 nm.
