Document Type and Number:
WIPO Patent Application WO/2023/005479
Kind Code:
A1
Abstract:
The present application relates to the technical field of battery production devices and to a lithium supplementation apparatus and a lithium supplementation method. The lithium supplementation apparatus comprises: a laminating mechanism, comprising a first roller, a second roller, and a third roller arranged adjacently in sequence, the first roller and the second roller being used for calendaring a lithium belt, the calendared lithium belt being attached to the second roller, the second roller and the third roller being used for laminating the lithium belt attached to the second roller to a substrate, and the lithium belt comprising two first surfaces opposite in the width direction of the lithium belt and a second surface facing the second roller; and a coating mechanism, along the belt moving direction of the lithium belt, the coating mechanism being provided on the upstream of the laminating mechanism, and the coating mechanism being configured to coat the second surface and at least one first surface with a release agent. The lithium supplementation device can avoid the sticking of the lithium belt to a roller and improve the production safety.
