摘要： One or more example embodiments of the present disclosure provide a positive active material, a rechargeable lithium battery including the same, and a method of preparing the same. The positive active material includes a lithium-containing composite oxide; and a sulfur-containing inorganic lithium compound, wherein the sulfur-containing inorganic lithium compound forms a coating layer on a surface of the lithium-containing composite oxide. The coating layer may reduce an amount of residual lithium and gas present on the surface of the lithium-containing composite oxide, thereby improving the stability of the battery and improving the cycle-life characteristics.
