It is primarily used in processes for the localised removal of electrode coatings. By precisely removing the positive or negative electrode coatings (such as ternary materials, lithium iron phosphate materials and graphite) from specific areas of the electrode (including the tab welding zone and edge blanking zones), it ensures the operational reliability of subsequent processes such as cell assembly, tab welding and encapsulation. Furthermore, it is a key piece of equipment for enhancing cell consistency, safety and cycle life.
