POSITIVE ELECTRODE, AND LITHIUM BATTERY INCLUDING THE SAME AND METHOD OF MANUFACTURE THEREOF

摘要

Disclosed are a positive electrode, a lithium secondary battery comprising the same, and a producing method thereof. The positive electrode comprises: a current collector; and a positive electrode active material layer arranged on at least one surface of the current collector and including a positive electrode active material. The positive electrode active material layer comprises: a first portion adjacent to the current collector; and a second portion adjacent to an outer surface of the positive electrode active material layer. Since the second portion includes a metal component, structural stability of the positive electrode can be improved. Accordingly, lifespan characteristics of a lithium battery comprising the positive electrode can be improved.
