Abstract:
The present invention provides a positive electrode active material for a secondary battery, the positive electrode active material being a primary particle having a monolithic structure that includes a lithium composite metal oxide of Formula 1 below, wherein the primary particle has an average particle size (D 50 ) of 2 μm to 20 μm and a Brunauer-Emmett-Teller (BET) specific surface area of 0.15 m 2 /g to 1.9 m 2 /g, and a secondary battery including the same.

Claim (Index 9):
A method of fabricating the positive electrode active material for a secondary battery of  claim 1 , the method comprising:\n a step of preparing a precursor by mixing a nickel raw material, a cobalt raw material, and an M1 raw material (here, M1 is at least one element selected from the group consisting of Al and Mn) and then performing a reaction; a step of mixing the precursor with a lithium raw material and an M3 raw material (here, M3 is any one or two or more elements selected from the group consisting of W, Mo, and Cr) such that a molar ratio of Li/Me (Me=the sum of metal elements in the precursor and the element M3) is 2.0 or higher and then sintering at 700\u00b0 C. to 900\u00b0 C. in the presence of a boron-based sintering additive; and a step of washing a product obtained by a result of the sintering such that a molar ratio of Li/Me\u2032 (Me\u2032=the sum of metal elements, excluding lithium, in the positive electrode active material) in the finally fabricated positive electrode active material is from 1.0 to 1.5 and then drying at 150\u00b0 C. to 400\u00b0 C.
