description Provided are a composite positive electrode active material, a positive electrode containing the same, and a lithium battery employing the positive electrode, wherein the positive electrode comprises: a first metal oxide represented by chemical formula 1, LiNi_xM^1_(1-x) O_(2-e)M'_e having a layered structure; and a second metal oxide having one or more crystal structures selected from layered, perovskite, halite, and spinel. The first metal oxide and the second metal oxide form a complex, and the mole fraction of the second metal oxide is greater than 0 and less than or equal to 0.2. In the chemical formula 1, M^1 is one or more elements selected from group 4 to 14 elements, and M' is an anionic element of F, S, Cl, Br, or a combination thereof, 0.7
