What is the effect of using a plasma cleaning machine to treat lithium batteries before welding?

Generally speaking, the production of lithium batteries includes three parts: electrode manufacturing, battery manufacturing, and battery assembly. There are several key technologies involved in these three major processes, and the performance of batteries produced by different production processes varies greatly. In these three processes, plasma cleaning machines can greatly improve the level of battery manufacturing technology. 

Plasma cleaning is a dry cleaning method that mainly relies on the "active action" of active ions in the plasma to remove surface stains. This method can effectively remove dirt and dust on the surface of the battery, thereby reducing battery welding. Today, let's explore together the operating process and application advantages of plasma cleaning machines in lithium batteries?

The positive and negative electrode plates of lithium batteries need to be cleaned during the coating of electrode materials. The metal strip is usually aluminum or copper, and traditional cleaning methods such as wet ethanol cleaning can easily damage other components of the lithium battery, treating the symptoms without addressing the root cause, and cannot quickly clean surface residues. In order to prevent safety accidents in lithium batteries,

 it is generally necessary to apply external adhesive treatment to the lithium battery to provide insulation, prevent short circuits, protect the circuit, prevent scratches, clean the insulation board and end plate, clean the dirt on the battery surface, roughen the battery surface. Therefore, it is necessary to use a plasma dry cleaning machine to effectively solve the above problems and improve surface adhesion.

Plasma is a state of matter in which a gas is heated to high temperatures, causing it to ionize and form a mixture of ions, electrons, and neutral particles alone. Plasma cleaning is a process that uses ionized gas for surface treatment to remove pollutants in lithium battery manufacturing. It enhances adhesion and improves overall performance by activating the surface before welding or coating. Plasma processing machines can activate the surface of lithium batteries, remove organic matter, and improve surface performance and adhesion;

1. The plasma cleaning machine can effectively remove organic residues, dust, and other pollutants from battery components, ensuring a clean surface for subsequent processes.

2. Low temperature plasma treatment can activate the surface of battery components and improve their wettability and adhesion to coating adhesives and other materials.

3. After treatment with a plasma cleaning machine, the adhesion and surface activation ability can be improved, which helps to enhance the performance, reliability, and durability of the battery.

4. Plasma cleaning is very important before welding battery components, as surface contaminants may cause poor welding and unreliable connections.

5. Plasma cleaning is used to clean the surfaces of battery components, tabs, electrodes, and other components before welding, coating, or bonding.

6. Plasma treatment can enhance the adhesion of coatings, films, and adhesive seals used in battery manufacturing, ensuring a strong and reliable connection between components.

7. Plasma cleaning can improve the performance, reliability, and durability of batteries, thereby enhancing their performance.

In summary, plasma cleaning is a dry cleaning method that mainly relies on the "activation effect" of active ions in the plasma to remove stains on the surface of objects. The above methods can effectively remove residual organic matter on the extreme end faces of batteries, prepare for battery welding in advance, and reduce defective welding products.
