The present invention relates to a manufacturing method of a positive electrode active material having reduced residual lithium, and to a positive electrode active material having residual lithium manufactured thereby. According to the present invention, the manufacturing method of a positive electrode active material having reduced residual lithium reduces the residual lithium by performing a reaction of Al, Ba, and B with the lithium remaining on a surface, and has effects in modifying the surface. The manufacturing method of a positive electrode active material having reduced residual lithium comprises: a first step of preparing a positive electrode active material; a second step of preparing a solution including Al, Ba, and B; a third step of coating the surface of the positive electrode active material with Al, Ba, and B; a fourth step of drying the coated positive electrode active material; and a fifth step of thermally treating the same.
