CATHODE ACTIVE MATERIAL COMPRISING LITHIUM TRANSITION METAL OXIDE PARTICLES, PREPARATION METHOD THEREOF, AND LITHIUM SECONDARY BATTERY COMPRISING THE SAME

摘要

The present invention relates to a cathode active material comprising lithium transition metal oxide particles and a first conductive material, the lithium transition metal oxide particles are comprised of second particles formed by flocculating at least two primary particles and the first conductive material is dispersed between the primary particles, and a method for manufacturing the cathode active material. The cathode active material according to an embodiment of the present invention can improve the performance characteristic of a secondary battery since the first conductive material is dispersed between the first particles in the lithium transition metal oxide so that the first conductive material forms networking with the first particles, thereby improving electrical conductivity.
