Positive electrode for nonaqueous electrolyte secondary battery and nonaqueous electrolyte secondary battery using the positive electrode

A positive electrode for nonaqueous electrolyte secondary batteries, comprising:

• a positive electrode active material composed of a mixture containing (i) lithium cobalt oxide particles having a surface to which rare-earth compound particles are partly adhered, and (ii) lithium nickel cobalt manganese oxide particles;
• and
• a binder,
• wherein the content of the lithium nickel cobalt manganese oxide is 1% by mass or more and 50% by mass or less relative to the total amount of the positive electrode active material,
• wherein the amount of the rare-earth compound particles adhered to the surface of the lithium cobalt oxide particles is 0.01% by mass or more and 0.5% by mass or less relative to the amount of the lithium oxide particles on a rare-earth element basis,
• wherein the rare-earth compound particles have an average particle size of 100 nm or less and 0.1 nm or more, and
• wherein the rare-earth compound particles are at least one selected from the group consisting of rare-earth hydroxides, rare-earth oxyhydroxides, and rare-earth carbonate compounds.
