Abstract
Proposed are an anode active material, a method for preparing the same, an electrode including the anode active material, and a rechargeable lithium battery including the same, in which when a discharge curve of a third charge-discharge cycle during a formation process, measured by incremental capacity analysis (ICA), is converted into a differential capacity versus voltage curve (dQ/dV) by normalizing the discharge curve with respect to the initial discharge capacity of each cell, the ratio of the maximum peak height observed in a voltage region of 3.0 to 3.3 V to the maximum peak height observed in a voltage region of 3.6 to 4.0 V is equal to or less than 60%.
