摘要： Embodiments of the present invention provide a cathode active material for a lithium secondary battery. The cathode active material for a lithium secondary battery includes lithium-transition metal composite oxide particles, and a coating formed on each of the lithium-transition metal composite oxide particles. The coating includes a lithium-sulfur compound and a metal hydroxide. A residual lithium on a surface of the cathode active material is sufficiently removed to improve an ionic conductivity and low-resistance.
