Abstract
This application relates to a composite positive electrode active material for a lithium secondary battery. The composite positive electrode active material includes a nickel-based active material and a cobalt-boron compound-containing coating layer formed on a surface of the nickel-based active material. The application also relates to a method of preparation of the composite positive electrode active material. The application further relates to a lithium secondary battery including a positive electrode containing the composite positive electrode active material.
