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.

Electrode plate forming apparatus

Provided an etching device that is capable of effectively realizing an opening structure with low cost and simplified process. The etching device includes: a porous roller, the porous roller being a hollow structure with openings at both ends, an etching liquid being accommodated in the hollow structure, and the porous roller being provided with a plurality of openings; a pressing roller, attached to the porous roller and arranged above the liquid level of the etching liquid, for pressing and attaching a metal layer to be etched onto the surface of the porous roller; wherein during rotation of the porous roller, the etching liquid passes through at least part of the openings of the plurality of openings and continuously soaks the metal layer in contact with the at least part of the openings, so as to continuously etch the metal layer in contact with the at least part of the openings.

Etching device

This application relates to a filtering mechanism and a device for producing a conductive material, where the filtering mechanism includes a filtering body, a cover, and a supporting member. The filtering body includes an accommodating cavity for accommodating an electroplating material and an opening provided on the filtering body; the cover is configured to cover the opening and connect to the filtering body to enclose the electroplating material in the filtering body; and the supporting member is provided on the cover to enhance connection strength between the cover and the filtering body.
