Multi-slot die, coating method using the same, slurry supply system, and slurry supply method using the same

A multi-slot die, comprising:

• a plurality of dies that form a continuous coating portion along a length direction on an electrode substrate that continuously proceeds in multiple columns to be spaced apart from each other along a width direction intersecting the length direction, using a supplied active material slurry;
• a plurality of gap adjustment assemblies that are provided corresponding to each of the dies and independently adjust gaps set between each of the dies and the electrode substrate along a discharge direction of each of the dies;
• a die position adjustment assembly that is provided corresponding to the gap adjustment assemblies and independently adjusts positions of the dies with respect to the width direction;
• and
• a plurality of die control units coupled to each of the dies to control the respective one of the gaps and the die position of each of the dies, wherein each of the die control units includes:
• a coupling member coupled to a coupling hole provided in each of the dies,
• a gap adjustment member adjusting the coupling member in a gap adjustment direction,
• a lifting plate including the coupling member and the gap adjustment member, and
• a lifting cylinder coupled to the lifting plate to be fixed to a side plate.
