Abstract
The present invention relates to a positive electrode active material for a lithium ion battery and, more specifically, to a positive electrode active material for a lithium ion battery, having improved initial capacitance and charging and discharging efficiency due to increased electrical conductivity or ion conductivity. The positive electrode active material for a lithium ion battery of the present invention contains lithium vanadium phosphate (LiV(PO)) and lithium zirconium phosphate (LiZr(PO)) formed on an external surface of the lithium vanadium phosphate. The positive electrode active material for a lithium ion battery comprising lithium vanadium zirconium phosphate (LiVZr(PO)) particles, which is prepared by a preparation method of the present invention, has excellent structural stability and ion conductivity as well as high capacitance.
