The present disclosure relates to a slot die coating apparatus for coating an electrode active material slurry onto an electrode collector, the slot die coating apparatus including: a coating roller; at least two or more dies; a discharge opening through which the electrode active material slurry is discharged in an opposite direction on which gravity acts; and an air vent installed in the die.

Slot die coating device having air vent

The present disclosure relates to a slot die coating apparatus for coating an electrode active material slurry onto an electrode collector, the slot die coating apparatus including a coating roller, a die comprising a lower discharge opening, through which a first electrode active material slurry is discharged, and an upper die located on the upper side of the lower die and having an upper discharge opening, through which a second electrode active material slurry is discharged, and an upper air vent may be installed in the upper die and a lower air vent may be installed in the lower die.

The present invention relates to a double slit coating die, and an electrode active material coating apparatus comprising same, the double slit coating die comprising first to fourth blocks which are positioned sequentially adjacent to each other, and having a structure in which the positions of the first and second blocks can move in a direction tilted at an angle &#x3b8; with respect to the interface between the second and third blocks. The present invention has the effects of preventing slip surfaces between blocks constituting the die from spreading apart, and reducing offset in a coating process.
