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.
