Abstract
A dry powder kneading apparatus includes a main body including an inner space into which a mixture containing an active material, a conductive material, and a binder is supplied, and a screw inside the inner space of the main body, the screw being configured to move the mixture in one direction and to knead the mixture into fiberized dry powder, and a rotation torque of the screw being 1.4 kgf·m to 42 kgf·m.
Claims19
A dry powder kneading apparatus, comprising:
- a main body including an inner space into which a mixture containing an active material, a conductive material, and a binder is suppliable;
- and
- a screw inside the inner space of the main body, the screw being configured to move the mixture in one direction and to knead the mixture into fiberized dry powder, and a rotation torque of the screw being 1.4 kgf·m to 42 kgf·m,
- wherein the screw includes:
- a conveyer configured to move the mixture in the one direction,
- a fiberizer connected to the conveyer, the fiberizer being configured to knead the mixture into the fiberized dry powder, and
- a blocker connected to the fiberizer, the blocker being configured to block movement of the dry powder in the one direction.
