    摘要： The present disclosure relates to a positive electrode active material precursor for a lithium secondary battery, a positive electrode active material manufactured by using thereof, and a lithium secondary battery comprising the same. More specifically, it relates to a positive electrode active material precursor for a lithium secondary battery as a secondary particle comprising transition metals, and formed by gathering of a plurality of primary particles having different a-axis direction length to c-axis direction length ratio , wherein the a-axis direction length to c-axis direction length ratio of the primary particle making up the secondary particle is increased from the center to the surface of the secondary particle; a positive electrode active material; and a lithium secondary battery comprising the same.
