What is the effect of plasma cleaning machine treatment on new energy batteries?
The seismograph plasma cleaning machine plays a key role in the digital manufacturing industry, and with the rapid development of electric vehicles and the gradual rise of the energy storage industry, these fields will also become the focus of future battery development. After years of rapid growth, the electronics industry is expected to continue to steadily grow and develop towards high energy density, large capacity, and lightweight. The reliability requirements for power battery packs are very high.
The battery of a car is an important component of the manufacturing and assembly process. How to use plasma cleaning technology to remove organic matter and small particles on the surface of lithium batteries, in order to improve the reliability of subsequent laser welding.
Automotive power batteries are divided into positive and negative electrodes. The positive and negative electrodes are part of the battery.
During the manufacturing process, lithium batteries often experience unevenness, bending, deformation, and other phenomena during the welding process. Using a plasma surface cleaning machine to treat the electrode surface can quickly remove impurities such as organic matter and coarse particles on the weld surface
The plasma surface cleaning machine can remove organic impurities such as oil stains, dust, and oxides on the electrode surface, making the surface cleaner, increasing surface roughness, improving surface energy, enhancing the bonding force between the two, and improving the cycling stability and service life of the battery.
The plasma cleaning machine can modify the surface of the electrode, optimize the interface performance between the electrode and the electrolyte, enhance the hydrophilicity of the surface, improve the safety of the battery, and extend the service life of the battery pack.
What is the difference between the seismograph plasma cleaning machine and the vacuum plasma cleaning equipment when treating lithium batteries?
Both atmospheric pressure plasma cleaning equipment and vacuum plasma cleaning equipment can perform nanoscale surface treatment on the surface of lithium batteries, removing pollutants, organic matter, and enhancing wettability.
I believe everyone is familiar with atmospheric pressure plasma cleaning machines and vacuum plasma cleaning machines.
Today, the editor will briefly explain the differences in the application of lithium batteries between the two:
1. The general atmospheric pressure plasma cleaning machine works under normal pressure without the need for a vacuum system. The equipment structure is relatively simple and usually equipped with a rotary plasma spray gun and a direct injection plasma nozzle, which can spray the plasma beam onto the surface of the workpiece. It can be integrated with an automated production line to achieve continuous processing and is suitable for cleaning large or irregular lithium battery workpieces.
2. The vacuum plasma cleaning machine requires the establishment of a vacuum environment inside a closed chamber, and is equipped with a vacuum pump group, a precision flow control system, and a pressure resistant chamber. The structure is complex and the cost is high.
3. In addition, low-temperature and atmospheric pressure plasma cleaning equipment is suitable for processing lithium battery materials with relatively flat surfaces. It has advantages in processing large output, online processing, flat workpieces, and large-area lithium battery workpieces. For example, in the large-scale continuous production of lithium battery electrode sheets, rapid cleaning and activation treatment of the metal foil surface is carried out to improve the adhesion of subsequent coating processes.
4. Vacuum plasma cleaning equipment can handle more complex and high-temperature resistant materials, suitable for processing lithium battery components with complex structures such as holes, indentations, wrinkles, etc., such as cleaning the interior of some lithium battery casings with special structures, and performing nanoscale surface treatment on some high-precision lithium battery electrode materials.
