Abstract
A system for extracting an active material residue from an assembly for coating an electrode with an active material layer, the system including a mobile tank configured to hold the active material residue, a conduit attachable to the mobile tank and releasably connectable to the assembly, and a pumping device configured to apply a negative pressure to the mobile tank to suck the active material residue from the assembly through the conduit.
Claims16
A system for extracting an active material residue from an assembly for coating an electrode with an active material layer, the system comprising:
- a mobile tank configured to hold the active material residue;
- a conduit attachable to the mobile tank and releasably connectable to the assembly;
- and
- a pumping device configured to apply a negative pressure to the mobile tank to suck the active material residue from the assembly through the conduit.
An assembly for coating an electrode with an active material layer, the assembly comprising:
- a stationary tank configured to store a supply of active material for processing in the assembly;
- a die coater configured to supply the active material onto a metal foil web material to form the active material layer;
- a conveyor configured to transfer the active material from the stationary tank to the die coater;
- an exit member including an exit aperture, the exit member being configured to selectively close or open the exit aperture for ejecting the active material from the assembly;
- and
- a system configured to extract active material residue from the assembly being releasably attached to the exit member.
A method for extracting active material residue from an assembly for coating an electrode with an active material layer, the method comprising:
- providing a mobile tank;
- attaching a conduit to the mobile tank;
- connecting the conduit to the assembly;
- and
- sucking active material residue from the assembly through the conduit into the mobile tank.
