Composite electrode active material, lithium battery including the same, and method of preparing the composite electrode active material

摘要

A composite electrode active material includes: a carbon nanostructure shell; a first core material disposed in a first pore channel of the carbon nanostructure shell; and a second core material disposed in a second pore channel of the carbon nanostructure shell, wherein the first core material includes a first electrode active material and the second core material includes a second electrode active material, and wherein the first electrode active material has a Li+/Li charge/discharge voltage potential which is different from a Li+/Li charge/discharge voltage potential of the second electrode active material.
