1. A multi-slot die coater comprising a first slot and a second slot to extrude and coat a coating solution on a surface of a continuously moving substrate through at least one of the first slot or the second slot, the multi-slot die coater comprising:
a first outer die block;
an intermediate die block positioned adjacent to the first outer die block such that the first slot is formed between the intermediate die block and the first outer die block; and
a second outer die block positioned adjacent to the intermediate die block such that the second slot is formed between the second outer die block and the intermediate die block,
wherein the die-coater includes a first contact surface between the first outer die block and the intermediate die block, and a second contact surface between the intermediate die block and the second outer die block that is inclined relative to the first contact surface, and a fastener is fastened substantially perpendicular to one of the first and second contact surfaces
wherein the intermediate die block includes a first intermediate die block and a second intermediate die block in surface contact with each other, the first intermediate die block and the second intermediate die block configured to slidably move along a third contact surface relative to each other,
the first intermediate die block is fixed and coupled to the first outer die block, and the second intermediate die block is fixed and coupled to the second outer die block, and
wherein the multi-slot die coater extends from a front end to a rear end opposite the front end, and wherein the third contact surface between the first intermediate die block and the second intermediate die block extends along a single plane from the front end to the rear end.
