What role does atmospheric plasma cleaning equipment play in the production of lithium battery pole pieces:
When it comes to automotive lithium batteries, I believe everyone is no longer unfamiliar with them. The production process of automotive lithium battery pole pieces is more complicated, including slurry preparation, slurry coating, pole piece rolling, pole piece slitting and pole piece drying. It is a relatively new process to use atmospheric plasma cleaning equipment to process the pole pieces before coating. Therefore, what role does atmospheric plasma cleaning equipment play in the manufacturing process of lithium battery positive and negative plates? How does this help the product?

The positive and negative electrode materials of the lithium battery are coated on the metal film to make the positive and negative electrodes of the automobile power lithium battery. Before the electrode material is coated, the metal film must be cleaned to improve the coating effect. The material of the metal film is generally aluminum foil or copper foil. In the past, the cleaning is done by wet processing. Even if the surface is cleaned with ethanol and other solutions, this cleaning method is likely to cause invisible damage to the lithium battery and other components. Will produce some residue.
Due to these shortcomings, in the subsequent manufacturing process, the dry surface treatment method of atmospheric plasma cleaning equipment is gradually adopted. It can not only remove organic matter, make the surface of the film rough, improve the wettability of the metal film surface, but also improve the coating. The uniformity of the layer is conducive to improving thermal stability, safety and reliability.
If you have any questions about the purchase or use of the equipment, please feel free to inquire.
