SURFACE-MODIFIED CATHODE ACTIVE MATERIALS BY CHEMICALLY CROSSLINKABLE POLYMER ELECTROLYTES AND LITHIUM ION RECHARGEABLE BATTERIES COMPRISING THE SAME

摘要

The present invention relates to a positive electrode active material, on the surface of which a chemically cross-linked polymer having movable lithium ions is formed. The present invention also relates to a method for preparing the positive electrode active material, and to a lithium secondary battery comprising the material.
