Abstract

A cathode for a lithium secondary battery includes a cathode current collector; and a cathode mixture layer on at least one surface of the cathode current collector, wherein the cathode mixture layer includes a first cathode mixture layer on the cathode current collector; and a second cathode mixture layer on the first cathode mixture layer, the first cathode mixture layer and the second cathode mixture layer respectively independently include lithium metal phosphate and lithium transition metal oxide as active materials, a weight of the lithium metal phosphate included in the first cathode mixture layer exceeds a weight of the lithium transition metal oxide, the first cathode mixture layer includes a spherical-type conductive material, and the second cathode mixture layer includes a needle-type conductive material.
