Abstract: This application discloses a lithiation device for applying a lithium film on an electrode plate. The lithiation device includes: a rolling mechanism including a first roller and a second roller, the two rollers configured to roll the electrode plate and the lithium film to apply the lithium film on the electrode plate; an adjustment mechanism connected to the rolling mechanism and configured to adjust a gap and/or a rolling force between the first roller and the second roller; a first monitoring mechanism configured to monitor a length of the electrode plate after the electrode plate passes through the rolling mechanism; and a controller configured to control the adjustment mechanism based on a comparison result of the length monitored by the first monitoring mechanism and a target length so that the length of the electrode plate after the electrode plate passes through the rolling mechanism approximates to the target length.

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.
