Why do many companies that produce power batteries put dust control in the first place?

In daily life, there are many dusts that cannot be recognized by the naked eye. However, natural phenomena such as rain, snow, and fog are inseparable from their participation.

With the improvement of manufacturing precision, the impact of dust on the entire production process has been paid more and more attention by people!

In the production process of lithium batteries, dust mainly comes from various links such as people, machines, materials, methods, and rings. If you disassemble a battery of poor quality, there is a high probability that you will find the existence of "black spots" on the diaphragm. These The black spots are basically caused by dust breakdown.

It can be said that dust is the fundamental cause of self-discharge of lithium batteries. If not paid attention to, it may lead to incalculable disasters such as internal short circuit of the battery, battery fire and explosion.

Three ways of dust removal in lithium battery production process

Principle of USC Dry Ultrasonic Dust Removal

The blower provides 8-16Kpa clean gas to the ultrasonic generating chamber to generate ultrasonic waves, and the energy and vibration of the ultrasonic waves are used to separate the dust particles from the material surface to achieve the purpose of dust removal. It is an efficient, safe and clean dry dust removal method.

USC dust removal scheme for the pole piece process section of a large lithium battery factory

The factory uses Shengding USC dry ultrasonic dust removal solution in the three processes of coating, die cutting and winding in the pole piece process section, which has been verified many times:

• 3μm dust particles can achieve 97% removal rate
• 6μm dust particles can reach 98% removal rate
