Abstract

The invention discloses a device for electrode slice production with a lithium strap. The device includes a lithium strap conveying mechanism, a lithium strap tab adding structure, a rubberizing mechanism, a lithium strap cutting mechanism and a feeding mechanism. The lithium strap tab adding mechanism comprises a tab conveying mechanism, a tab knurling mechanism and a tab laminating mechanism. The tab conveying mechanism is used for conveying a tab to a lithium strap conveying path of the lithium strap conveying mechanism and cutting it off. The tab knurling mechanism is positioned on a tab conveying path of the tab conveying mechanism for knurling of the tab to make it have an uneven surface. The tab laminating mechanism is used for laminating the knurled tab to the lithium strap. The invention also discloses a method for electrode slice production with a lithium strap. The device and method of the invention can overcome the defects existing in traditional modes of electrode slice production with lithium straps, and improve the quality and automation level of electrode slice production with lithium straps.
