PRECURSOR PARTICLES OF LITHIUM COMPOSITE TRANSITION METAL OXIDE FOR LITHIUM SECONDARY BATTERY, AND CATHODE ACTIVE MATERIAL CONTAINING SAME

摘要

Disclosed are precursor particles of a lithium composite transition metal oxide for lithium secondary batteries, wherein the precursor particles of a lithium composite transition metal oxide are composite transition metal hydroxide particles including at least two transition metals and having an average diameter of 1 µm to 8 µm, wherein the composite transition metal hydroxide particles exhibit monodisperse particle size distribution and have a coefficient of variation of 0.2 to 0.7, and a cathode active material including the same.
