  "textContent": "The present invention relates to a positive electrode active material which may improve high-temperature life characteristics and high-temperature storage characteristics of a lithium secondary battery, and a positive electrode and a lithium secondary battery which include the positive electrode active material. Specifically, the present invention relates to a bimodal positive electrode active material including a first lithium transition metal oxide and a second lithium transition metal oxide having an average particle diameter (D50) smaller than that of the first lithium transition metal oxide, wherein the first lithium transition metal oxide has higher particle strength and smaller crystalline size than the second lithium transition metal oxide, and a positive electrode and a lithium secondary battery which include the positive electrode active material.",
