摘要
A positive electrode active material for a lithium secondary battery, which includes a lithium-containing composite metal compound in the form of secondary particles that are aggregates of primary particles capable of being doped and undoped with lithium ions, each of the secondary particles having on its surface a coating layer including a metal composite oxide including lithium and aluminum, wherein the positive electrode active material includes at least nickel and aluminum as non-lithium metals, and satisfies all of the requirements (1) to (2).
