Abstract
The present application provides an electrode tab structure and a battery, the electrode tab structure includes: an electrode tab substrate; a current collector connected with the electrode tab substrate, a largest thickness after the electrode tab substrate being welded with the current collector is less than or equal to 1.5 times of a sum of a thickness of the electrode tab substrate and a thickness of the current collector. In the present application, the thickness of the electrode tab structure is suitably limited with respect to the sum of the thickness of the electrode tab substrate and the current collector, which avoids defect of too large welding resistance caused by too large thickness of the electrode tab structure, so as to improve internal symmetry of the cell, increase the reliability of the electrode tab structure, and avoid from deforming, which thereby improving the overall performance of the battery.
