A positive active material for a rechargeable lithium battery is provided. The positive active material includes at least one compound selected from the group consisting of lithiated compounds, a metal oxide layer formed on a surface of the compound and metal oxide masses adhered on the metal oxide layer. The positive active material is produced by coating a compound with a metal alkoxide solution, an organic solution of a metal salt or an aqueous solution of a metal salt and heat-treating the coated compound. The compound is selected from the group consisting of lithiated compounds. Thereafter, the heat-treated compound is slow-cooled to 100 to 500° C. and the cooled compound is quenched to room temperature. |
