Abstract

See full text

The present invention relates to a method of preparing a positive electrode material for a lithium secondary battery including a first step of synthesizing a lithium transition metal oxide represented by Chemical Formula 1, a second step of preparing lithium transition metal oxide powder by grinding the lithium transition metal oxide, a third step of preparing a positive electrode material including an alumina coating layer by mixing as well as dispersing the lithium transition metal oxide powder in an alumina nanosol, and a fourth step of drying the positive electrode material, a positive electrode material for a lithium secondary battery prepared by the above method, and a lithium secondary battery including the positive electrode material,
