Abstract

The present invention relates to a method for preparing a positive electrode active material, the method comprising the steps of: mixing a nickel-containing hydroxide precursor containing 65 mol% or more of nickel relative to the total number of moles of transition metals and a lithium raw material, followed by primary thermal treatment, to prepare a nickel-containing lithium transition metal oxide; mixing a B and C-containing raw material and a Co-containing raw material with the nickel-containing lithium transition metal oxide to form a mixture; and subjecting the mixture to secondary thermal treatment to form a coating material containing B and Co on a surface of the lithium-transition metal oxide, to a positive electrode active material prepared by the preparation method and having a coating material containing a particular content of Co, to a positive electrode, containing the positive electrode active material, for a lithium secondary battery, and to a lithium secondary battery.
