Abstract
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 θ 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.
