Abstract

An active material for a lithium secondary battery according to exemplary embodiments may have a peak ratio index (S) of 100 to 500, as defined by Equation 1 below: S=A/B (wherein A denotes the maximum peak intensity in the 4.2 V to 4.3 V region of the differential capacity (dQ/dV) discharge graph, and B denotes the peak intensity at 4.5 V in the dQ/dV discharge graph). Therefore, the cathode active material may exhibit excellent structural stability and may provide a secondary battery with improved cycle life characteristics.
