    摘要： The present invention relates to an electrode lead for a rechargeable battery, wherein a corrosion-preventing protection layer is selectively formed on only that portion of the electrode lead which is positioned outside the cell, and relates to a rechargeable battery comprising the same. When the present invention is employed, it is possible to reduce the resistance of the cell while at the same time preventing corrosion of the electrode lead from an external environment, by forming the corrosion-preventing protective layer selectively on only that portion of the electrode lead which is positioned outside the cell.
