Abstract: A device for supplementing an electrode plate with lithium and a method for supplementing an electrode plate with lithium. The device for supplementing an electrode plate with lithium includes a first lithium strip unwinding mechanism, an electrode plate unwinding mechanism, a roller pressing mechanism, a first traction mechanism, an electrode plate winding mechanism, and a first coating mechanism. The first lithium strip unwinding mechanism is configured to dispose a lithium strip, and the electrode plate unwinding mechanism is configured to dispose an electrode plate. The roller pressing mechanism includes a first calendering roller, a first laminating roller, and a second laminating roller. In a traveling direction of the lithium strip, the first coating mechanism precedes the roller pressing mechanism, and the first coating mechanism is configured to apply a coating layer on a surface of the lithium strip.

Abstract: A lithium strip that can be used in lithium supplementation equipment is described. The lithium strip has a first surface, and a thinned area is formed at the edge of the first surface along the width direction of the lithium strip to form a space for accommodating a release agent at the thinned area. The thinned area is designed to enable the lithium strip to pick up more release agent when it is applied to a coating device, and the release agent can remain in the above thinned area. The presence of the thinned area in the lithium strip can reduce the lithium load per unit width, so that during the calendering process of the lithium strip, there will be no calendering exceeding the preset width, so that the lithium strip will not stick to the roller after calendering.
