APPARATUS AND METHOD OF DISCHARGING DRY ELECTRODE MIXTURE

A method of discharging a dry electrode mixture, includes mixing the dry electrode mixture in a mixer, and disposing a movable pipe in the mixer and performing vacuum transport of the dry electrode mixture through a suction part of the movable pipe. The method comprises mixing the dry electrode mixture, including an electrode active material, conductive material, and binder, in a mixer with a rotatable chamber and blades. A movable pipe with a suction part, having a lower hole and vertically elongated side openings, is positioned within the mixer. A sensor detects the pipe's position to perform iterative discharge cycles, incrementally lowering the pipe until a predetermined lower set position is reached. The final discharge cycle is conducted with the chamber rotating at low speed, after which the pipe is raised. The system includes a movable pipe, suction part, and vacuum conveyor, enabling efficient, clumping-minimized discharge.
