Laser Cleaning | Popular Applications in Lithium Battery Manufacturing
Laser cleaning has always been one of the research hotspots in the field of industrial manufacturing. With the vigorous development of the new energy industry, the demand for lithium batteries has increased sharply, and new tasks and challenges have been proposed for the cleaning process in the manufacture of lithium batteries. In the past two years, under the vigorous promotion of head laser companies, laser cleaning has been maturely applied to the manufacturing process of new energy batteries, and has moved from an industrial substitute to a dominant stage.
As a national high-energy laser technology enterprise, New Start Laser has always been guided by the market and centered on customer needs. While focusing on the innovation and breakthrough of intelligent laser cleaning technology, it has been deeply expanding its application in the industrial field. Among them, in the lithium battery manufacturing process, the new starting point laser intelligent cleaning technology also provides "new ideas", such as pole piece cleaning, new energy battery shell cleaning, etc.
Pole cleaning
In the lithium-ion battery manufacturing process, before the tabs are welded, the coating on the area of the tabs to be welded needs to be cleaned off to ensure the stability of the current collector inside the battery. The methods of removing the coating mainly include mechanical scraping, chemical cleaning and laser cleaning. Among them, mechanical scraping and chemical cleaning all have weaknesses such as regular shutdown to replace consumables, easy damage to the pole piece, and difficulty in ensuring that the coating is removed cleanly.
Different from traditional cleaning methods, New Start Laser successfully explored the critical parameter values of foil damage and coating residue, and launched intelligent laser cleaning technology and equipment, which has the advantages of green environmental protection, high cleanliness, no consumables and low cost. While efficiently removing the surface coating of products of different cleaning sizes, it can also improve the performance of the foil and ensure the internal stability of the battery.
