A dual slot die coater, comprising:
- a first die block provided with a first manifold for accommodating a first coating material,
- a second die block provided on one side of the first die block,
- a third die block interposed between the first die block and the second die block,
- a second manifold provided in either the second die block or the third die block and accommodating a second coating material, and
- a temperature controller provided in the first die block and capable of controlling temperature.
A method of manufacturing an electrode using a dual slot die coater, the method comprising:
- a step of setting a supply pressure for a coating material to set a supply pressure of a first coating material inside a coating material supply line, which is for supplying the first coating material to a first manifold of a first die block,
- a step of measuring pressure to measure an internal supply pressure of the coating material supply line,
- a step of lowering temperature to lower temperature of the first coating material accommodated within the first manifold when a supply pressure of the first coating material inside the coating material supply line, as measured in the step of measuring pressure, is lower than the supply pressure set in the step of setting a supply pressure for a coating material, and
- a step of raising temperature to raise temperature of the first coating material accommodated within the first manifold when a supply pressure of the first coating material inside the coating material supply line, as measured in the step of measuring pressure, is higher than the supply pressure set in the step of setting a supply pressure for a coating material.
