7. Winding is required during the production of prismatic and cylindrical cells. During winding process, the dust generation point depends upon the shape of battery.
Square battery: During the winding process, the main dust generating points are the powder brush and the main shaft winding area. (that is, the pole piece cutting position)
Cylindrical battery: The main dust production points of the cylindrical battery are the powder (or blowing and suction) box, the welding point of the pole lug, and the winding area of the main shaft (that is, the position where the pole piece is cut off), which produces a certain amount of smoke and cutting chips or particles. The dust remover machine can help remove dust in places prone to dust, which is more convenient and cleaner than manual dust removal. A dust remover machine will be the best way to remove dust.
8. During the packaging process of cell assembly, the jelly roll’s edges are compressed, fixed, and ultrasonically welded to the contact terminals attached to the battery’s lid. An insulation foil protects the jelly roll during insertion into the prismatic housing. And the housing is often sealed by a laser welding process.
New technologies arising in the wake of a spike in lithium-ion battery manufacturing are subjected to meet special environmental protection requirements. A proper dust remover machine and extraction system are necessary to provide protection against harmful contaminants produced during the manufacturing of Li-ion batteries.
