Electrode Coating Die, Electrode Coating Apparatus, Electrode Manufacturing Method, Electrode, Electrode Assembly, And Secondary Battery

Abstract: The present invention provides an electrode coating die and an electrode coating apparatus comprising same, the electrode coating die comprising: a slurry discharge unit for discharging an active material slurry onto a current collector; and a dam liquid discharge unit, provided on at least one side of the slurry discharge unit, for discharging a dam liquid to form a dam layer covering at least a portion of an inclined surface unit provided at an edge portion of an active material slurry layer applied by being discharged from the slurry discharge unit. In addition, the present invention provides an electrode manufacturing method comprising: a step of preparing an active material slurry including an active material, a conductive material, and a solvent; and a coating step of applying the active material slurry on a current collector, wherein the coating step comprises a step of forming an active material layer by discharging the active material slurry on the current collector while simultaneously discharging a dam liquid to form a dam layer covering at least a portion of an inclined surface unit provided at an edge portion of at least one side of an active material slurry layer coated on the current collector.
