CATHODE ACTIVE MATERIAL OF SURFACE TREATMENT FOR SECONDARY BATTERY AND METHOD OF PREPARING THE SAME

摘要

The present invention relates to a positive electrode active material for secondary batteries with treated surface and a manufacturing method thereof and, more specifically, a positive electrode active material for secondary batteries with treated surface, which is manufactured by making lithium transition metal oxide having a specific element react with a coating precursor and accordingly forming a complex coating layer including the transition metal derived from the lithium transition metal oxide, and a manufacturing method thereof.
