METHOD FOR MANUFACTURING ELECTRODE, ELECTRODE MANUFACTURED BY METHOD, AND LITHIUM SECONDARY BATTERY INCLUDING ELECTRODE

摘要

The present invention relates to a method for manufacturing an electrode, the electrode manufactured by the method, a lithium secondary battery including the electrode, and a flexible lithium secondary battery including the electrode, and the method comprises the steps of: forming an uneven pattern on a surface of a current collector by using a wet etching method, a dry etching method, or a roll-to-roll method; and growing an active material on the patterned surface of the current collector.
