POSITIVE ELECTRODE ACTIVE MATERIAL PRECURSOR FOR LITHIUM SECONDARY BATTERY, POSITIVE ELECTRODE ACTIVE MATERIAL MANUFACTURED BY USING THEREOF, AND LITHIUM SECONDARY BATTERY INCLUDING SAME |
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. |
