Plasma cleaning in 3 applications in the lithium battery industry

Plasma cleaning in 3 applications in the lithium battery industry

In general, the production of lithium batteries includes three parts: pole piece manufacturing, cell manufacturing, and battery assembly. There are several key processes in these three large processes, and the battery performance produced by different production processes varies greatly. Increasing plasma cleaning in three processes can greatly improve the battery manufacturing process.

1. Plasma cleaning before pole piece coating

The cathode and anode electrodes of a lithium battery are formed by coating a positive and negative materials of a lithium battery on a metal strip. When the metal strip is coated with an electrode material, the metal strip needs to be cleaned. The metal strip is generally thin or thin. The copper is thin and the original wet ethanol cleaning is easy to damage other parts of the lithium battery. The plasma dry cleaning machine effectively solves the above problems.

2. Plasma cleaning before battery welding

Plasma cleaning is a kind of dry cleaning, which relies on the "activation" of active ions in plasma to achieve the purpose of removing stains on the surface of objects. This method can effectively remove dirt, dust, etc. from the end face of the cell pole, and prepare for battery welding in advance to reduce defective soldering.

3. Medium ion cleaning during battery assembly

In order to prevent a lithium battery from a safety accident, it is generally necessary to externally apply a lithium battery cell to act as an insulator to prevent the occurrence of a short circuit, protect the circuit, and prevent scratches. Clean the insulation board and the end plate, clean the surface of the battery core, roughen the surface of the battery core, and improve the adhesion of the glue or glue.
