- Abstract
- Slitting, which is supposed to be one of the most critical processes in Li-Ion battery manufacturing, is supposed to cut off the uncoated parts of the foil, and cut the wide foils into the size of the Li-ion batteries. Vibrations of slitting machines are the most critical factors for uneven cut surface such as surface roughness and burr, which are the main reasons of the tearing of microporous membranes to separate the cathodes and the anodes, and eventually causing explosion of the batteries. In this study, the structure of a slitting machine has been analyzed through computer simulations to figure out the main reasons of the vibrations. The result of the study shows that simple design alterations of the supporting area and roller without modifying the main structure of the machine can suppress the vibrations effectively, and further to prevent the devastating explosion.
