Abstract
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 a carbon-based active material, a first silicon-based active material including a carbon-silicon composite active material, and a second silicon-based active material including a silicon oxide (SiOx, 0<x<2). A content of the first silicon-based active material is in a range from 2 wt % to 40 wt % based on a total weight of the anode active material layer.
