  • Connecting structure and method between grid and electrode tab of secondary battery
    Patent number: 10056597
    Abstract: Disclosed is a connecting structure and method between a grid and an electrode tab of a secondary battery, which may ensure stable connection between the grid and the electrode tab of an electrode assembly and allow improved productivity. The connecting structure includes a grid integrally extending from an electrode plate of a secondary battery, an electrode tab connected to the grid, and a laser welding portion connecting the grid and the electrode tab. Also, a connecting method between a grid and an electrode tab of a secondary battery includes (a) fixing the grid with a jig, (b) cutting the grid, and (c) stacking the grid and the electrode tab and connecting the grid and the electrode tab by means of laser welding.
