Dust Control for Lithium-ion Battery Stacking

Staking

After notching, the electrode sheets are conveyed to thestacking machine.

There is relatively little dust generated when the pole pieces are conveyed to the stacking machine, the primary role of the dust collector is to provide suction force, preventing the sheets from moving during transportation.

Through a repeated Z-folding process, the positive and negative electrode sheets are stacked together with the separator to assemble a bare cell.

Solutions

Dust may also be generated during the stacking process, necessitating the implementation of dust removal either at the suction inlet of the stacking machine or by using a side suction hood at the stacking location.
