Abstract
Provided are an electrode lead of a secondary battery where a protection layer for anti-corrosion is selectively formed at an electrode lead portion at the cell outside and a secondary battery including the same. Since a protection layer for anti-corrosion is selectively formed only on an electrode lead portion at the cell outside, the corrosion of the electrode lead may be prevented from an external environment and the resistance of a cell may be reduced simultaneously.
