摘要: Provided are a positive electrode, a lithium battery including the positive electrode, and a method of manufacturing the positive electrode. The positive electrode may include: a composite positive active material and a binder. The composite positive active material may include: a core including a lithium transition metal oxide; and a shell on and conformed to a surface of the core. The shell may include: at least one first metal oxide represented by Formula MaOb; and a carbonaceous material. The at least one first metal oxide may be in a carbonaceous material matrix, and M may be at least one metal selected from Groups 2 to 13 and 15 and 16. The positive active material layer may include a carbonaceous conductive agent, and the carbonaceous conductive agent may be present only in the shell.
