Abstract
Provided are a metal element-doped positive electrode active material for a high voltage and a preparation method thereof. The positive electrode active material may include a lithium cobalt oxide having a layered crystal structure; and a metal element (M) incorporated into the lithium cobalt oxide in an amount of 0.2 parts by weight to 1 part by weight with respect to 100 parts by weight of the lithium cobalt oxide, wherein the metal element (M) does not form a chemical bond with the elements of the lithium cobalt oxide, and wherein the layered crystal structure in maintained at a positive electrode potential of more than 4.5 V (based on Li potential) when fully charged.
