摘要： An electrode plate forming apparatus includes an unwinding device, a lithium replenishment device, a plurality of winding devices and a protection device. The lithium replenishment device is configured to clad a lithium strip to a surface of a master electrode plate body and form a master electrode plate. A slitting device is configured to slit the master electrode plate into a plurality of electrode plates. The winding devices are configured to pull the electrode plates to travel, each of the winding devices winding one corresponding electrode plate. The slitting device is disposed in an accommodating cavity of the protection device. The protection device is configured to at least partially separate particles from an external environment in a case that the slitting device slits the master electrode plate and generates the particles.

摘要： 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.
