Abstract
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.
