The present invention relates to electrode slurry coating apparatus and method, the present invention ultimately allowing the process efficiency to be increased and rate of errors to be reduced when double-layer structured active material layers are formed by temporally adjusting the height of first and second discharge outlets through which active material is discharged.

Electrode slurry coating apparatus and method for forming double active material layers

The present invention relates to an electrode slurry coating device and method, wherein the heights of first and second slot die heads for discharging active material can be controlled according to time to improve process efficiency and reduce defect rates when forming an active material layer having a double layer structure.

Secondary battery electrode plate including electrode mixture regions having different binder content, and method for manufacturing secondary battery electrode using same

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.
