MANUFACTURING METHOD OF CATHOD ACTIVE MATERIAL FOR LITHIUM RECHARGEABLE BATTERY AND CATHOD ACTIVE MATERIAL MADE BY THE SAME

摘要

The present invention relates to a lithium complex oxide for a lithium secondary battery and, more specifically, to a positive electrode active material having high thermal stability and thermal efficiency obtained by adjusting a concentration of manganese at an inner core and an outer bulk portion, regarding a lithium transitional metal oxide having a concentration gradient.
