Claim:
A positive electrode comprising an active material, wherein substantially all of the active material of said electrode includes a lithium transition metal complex oxide, used for a non-aqueous electrolyte secondary battery, wherein an oxide of at least one dissimilar element, selected from elements of aluminum, silicon, titanium, vanadium, chromium, iron, nickel, copper, zinc, zirconium, molybdenum, tungsten and lead, and dissimilar to elements constituting the lithium transition metal complex oxide, is intermixed with all of the lithium transition metal complex oxide, and wherein an intermixture amount of the oxide is set such that a sum of a molar number of the at least one dissimilar element contained in one gram of the positive electrode active material to a molar number of lithium contained in one gram of the positive electrode active material is between one and five thousandths.
