摘要：
A composite positive electrode active material includes: a first metal oxide that has a layered structure and is represented by Formula 1; and a second metal oxide that has a spinel structure and is represented by Formula 2, wherein the composite positive electrode active material includes a composite of the first metal oxide and the second metal oxide: LiMO2 Formula 1 LiMe2O4 Formula 2 wherein, in Formulas 1 and 2, M and Me are each independently at least one element selected from Groups 2 to 14 of the periodic table, and a molar ratio of Li/(M+Me) in the composite is less than 1.
