Device for supplementing electrode plate with lithium and method for supplementing electrode plate with lithium

A method for supplementing an electrode plate with lithium, comprising

• disposing a lithium strip to a first lithium strip unwinding mechanism, and disposing an electrode plate to an electrode plate unwinding mechanism;
• connecting an end of the lithium strip to a first traction mechanism, wherein the first traction mechanism draws the lithium strip to travel and pass through a first coating mechanism, and the first coating mechanism applies a coating layer on a surface of the lithium strip;
• drawing the lithium strip coated with the coating layer into between a first calendering roller and a first laminating roller under the traction of the first traction mechanism, wherein the first calendering roller and the first laminating roller rotate and thin the lithium strip, and the lithium strip is adhered to a roller surface of the first laminating roller and separated from the first traction mechanism;
• and
• drawing the electrode plate to pass through between the first laminating roller and the second laminating roller and connect to an electrode plate winding mechanism, wherein
• the first laminating roller and the second laminating roller roll the electrode plate and the lithium strip on the roller surface of the first laminating roller, to laminate the lithium strip to the surface of the electrode plate.
