Plasma Cleaning Machine Plasma Cleaner Plasma Surface treatment for Battery Surface Cleaning

Why need plasma clearning for battery?

During the production, testing and transportation of lithium battery cells, impurities such as dust and metals will stick to the positive and negative terminals. This brings trouble to the subsequent assembly of the battery pack, resulting in poor spot welding effect. Therefore, it needs to be plasma cleaned before assembly to maintain a clean terminal.

The principle of plasma cleaning is mainly
(A)Etching on the surface of materials - physical effects
A large number of active particles in the plasma, such as a large number of ions, excited molecules, and free radicals, act on the
surface of the solid sample, which not only removes the original contaminants and impurities, but also produces an etching effect
to roughen the surface of the sample. Many fine pits are formed, increasing the surface ratio of the sample. Improve the wetting
properties of solid surfaces.
(B)Activation bond energy, cross-linking
The energy of the particles in the plasma is between 0-20 eV, and most of the bonds in the polymer are between 0-10 eV.
When a solid surface is used, the original chemical bond on the solid surface can be broken, and the free radicals in the plasma
and these bonds
The formation of a network of crosslinked structures greatly activates surface activity.
(C)Forming new functional groups - chemistry
If a reactive gas is introduced into the discharge gas, a complicated chemical reaction occurs on the surface of the activated
material, and new functional groups such as a hydrocarbon group, an amino group, a carboxyl group, and the like are introduced,
and these functional groups are all active groups, which can significantly improve the surface activity of the material.
