| description | The present invention relates to an electrode having an improved electrode tab welding characteristic, which includes one or more non-coated-part electrode tabs of the same polarity stacked on each other to maintain welding safety regardless of an increase in the number of stacked electrode layers in order to realize high output and high capacity, and a secondary battery comprising the same. The present invention can prevent disconnection which may occur when a plurality of electrode tabs are welded. Also, in the present invention, a lower end portion of an electrode lead, which is to be welded to the non-coated-part electrode tabs of the same polarity stacked on each other, is pressed to correspond to the non-coated-part electrode tabs. Therefore, the present invention can enhance the flexibility of an electrode step difference in a secondary battery.
本文公开一种构造为使得给具有相同极性的多个堆叠的电极提供一个或多个未涂覆电极接片，从而在为了实现高输出和高容量而增加堆叠的电极层的数量的情况下，保持焊接安全性的具有改善的电极接片焊接特性的电极及包括该电极的二次电池。因此，可在焊接电极接片时防止多个电极接片被切断。此外，焊接到提供给具有相同极性的多个堆叠的电极的未涂覆 |
