Abstract
Cathode active materials for lithium secondary batteries and lithium secondary batteries including the cathode active materials are disclosed. In some implementations, a cathode active material for a lithium secondary battery includes a lithium metal phosphate particle having a crystallite size in a range from 150 nm to 450 nm in a direction of a crystallographic plane (020) as measured by an X-ray diffraction (XRD) analysis. In some implementations, a lithium secondary battery includes a cathode including a cathode active material layer that includes a cathode active material for a lithium secondary battery, and an anode facing the cathode. In some implementations, an electrode crystallite size ratio defined by Equation 4 is in a range from 0.5 to 0.9.
