A cathode for a lithium secondary battery according to embodiments of the present invention includes a cathode current collector, and a cathode active material layer formed on the cathode current collector. The cathode active material layer includes first lithium metal oxide particles each having a secondary particle shape in which primary particles are aggregated and second lithium metal oxide particles each having a single particle shape. A cross-section of the cathode active material layer from an SEM satisfies Equations 1 and 2.
