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.
