Slot die for manufacturing rechargeable battery electrode, rechargeable battery electrode, and manufacturing method using the same

Abstract

A slot die for manufacturing a rechargeable battery electrode according to an embodiment includes a first block; a second block disposed on the first block; a third block disposed opposite to the second block; and a shim member that is disposed between the second block and the third block and forms a slot outlet in a width direction and a height direction. The first block forms a first cavity that receives an active material slurry supplied between the first block and the second block and forms a connection passage between the first block and the second block in a width direction and the height direction of the slot outlet. The second block forms a second cavity that receives the active material slurry supplied through the connection passage and discharges the received active material slurry through the slot outlet.
