cr2032 button battery

What are the applications of plasma cleaning in the cr2032 button battery industry?

The production and manufacturing of lithium-ion batteries is closely linked by process steps. Generally speaking, the production of lithium batteries includes three parts: pole piece manufacturing, battery cell manufacturing and battery assembly. There are several key processes in these three major processes, and the performance of batteries produced by different production processes varies greatly. Adding plasma cleaning to the three processes can greatly improve the level of battery manufacturing technology.

Plasma cleaning before pole piece coating

The positive and negative pole pieces of lithium batteries are made by coating the positive and negative electrode materials of lithium batteries on metal strips. When coating the electrode materials, the metal strips need to be cleaned. The metal strips are generally aluminum or copper. The original wet ethanol cleaning is easy to damage other parts of the cr2032 button battery. Plasma dry cleaning machine effectively solves the above problems.

Plasma cleaning before battery welding

Plasma cleaning is a dry cleaning method that mainly relies on the "activation effect" of active ions in plasma to remove stains on the surface of objects. This method can effectively remove dirt and dust from the end faces of the battery poles, prepare for battery welding in advance, and reduce defective welding products.

Plasma cleaning during battery assembly

In order to prevent safety accidents of lithium batteries, it is generally necessary to apply glue to the cr2032 button battery cells to play an insulating role, prevent short circuits, protect the circuits, and prevent scratches. Clean the insulating plates and end plates, clean the dirt on the surface of the battery cells, roughen the surface of the battery cells, and improve the adhesion of the glue or glue coating.

Relying on the "five effects" of active particles in plasma, enhance the effects of bonding, laminating, welding, coating, bonding, and glue removal. The pollutants removed may be organic matter, epoxy resin, photoresist, oxide, micro-particle pollutants, etc. Different cleaning processes should be used for different pollutants, and different process gases should be selected.
