Abstract

The present invention provides an electrode coating die, including: a slurry discharge part configured to discharge an active material slurry onto a current collector; and a dam liquid discharge part provided on at least one side of the slurry discharge part and configured to discharge a dam liquid to form a dam layer covering at least a portion of an inclined surface portion provided at an edge portion of an active material slurry layer coated with an active material slurry discharged from the slurry discharge part, and an electrode coating apparatus including the same. Further, the present invention provides a method of manufacturing an electrode, the method including: a preparing operation of preparing an active material slurry including an active material, a conductive material, and a solvent; and a coating operation of applying the active material slurry on a current collector, in which the coating operation includes forming an active material layer by discharging the active material slurry onto the current collector and discharging a dam liquid so as to form a dam layer covering at least a portion of an inclined surface portion provided on an edge portion of at least one side of an active material slurry layer coated on the current collector at the same time.
