Dust Control for Lithium-ion Battery Coating

Coating

After mixing, the mixture of electrode material is evenly coated onto a metal foil, followed by drying and winding.

Solutions

It ensures the consistency of pole piece thickness and weight while preventing the inclusion of particles, dust, or contaminants in the electrodes, which is critical for maintaining battery uniformity and safety.

After drying, a set of brushes is typically employed to roll and clean both sides of the electrode, eliminating surface dust.

To deal with the dust generated during the cutting position in winding, an integrated hood is used to enclose the cutting mechanism and perform dust removal.
