Description

Technical Field

[0001] This utility model relates to the field of lithium battery production technology, and in particular to a picosecond laser forming machine. Background Technology

[0002] A lithium-ion battery cell consists of five parts: electrodes, separator, tabs, electrolyte, and packaging film. Electrodes typically refer to electrodes containing active materials that undergo a reduction reaction during discharge, possessing a high potential. Lithium-ion battery electrodes are a granular coating evenly applied to a metal current collector. Simply put, they are the core of the cell; one electrode is positive and the other negative, allowing electricity to flow. The tabs extend the electrodes and connect them to other components to conduct electricity.

[0003] In the electrode processing process, the electrode is cut into smaller pieces and then slit to form smaller electrodes. Currently, the common practice in the market is to first transport the electrode to a laser cutting machine to cut the tabs and then roll it up. Then, the electrode with the tabs cut is transported to a die-cutting and slitting machine to be die-cut and slit to form smaller electrodes. This method requires repeated winding and transporting of the electrode, which not only wastes labor and time costs but also results in low production efficiency. Utility Model Content
