NOVEL PRECURSOR FOR CATHODE ACTIVE MATERIAL AND PREPARING METHOD THEREOF AND CATHODE ACTIVE MATERIAL USING THE SAME

摘要

The present invention provides an electroconductive cathode active material precursor including a complex transition metal hydroxide system and a complex transition metal oxide system, a method for producing the precursor, and a cathode active material for a secondary battery manufactured from the precursor. The present invention provides a positive electrode active material precursor including a composite transition metal oxide system and a hydroxide system having a large specific surface area and improved electrical conductivity of the powder, thereby improving the output characteristics of the secondary battery comprising the positive electrode active material produced from the precursor have.
