Slot die, slot die temperature control apparatus, and slot die temperature control method

A slot die temperature control apparatus comprising:

• a slot die including:
• an upper die;
• a lower die forming a gap with the upper die;
• a slurry supply unit configured to be connected to an external slurry supply source;
• one or more cavities formed in the lower die and connected to the slurry supply unit;
• a slot connected to the one or more cavities to coat a slurry on a base material;
• a temperature controller provided adjacent to the slot to control a temperature of the slurry discharged from the slot;
• and
• a temperature sensor configured to measure the temperature of the slurry;
• and
• a controller configured to control the temperature controller based on the temperature of the slurry measured by the temperature sensor.

• a slot connected to the one or more cavities to coat a slurry on a base material;
• a temperature controller provided adjacent to the slot to control a temperature of the slurry discharged from the slot;
• and
• a temperature sensor configured to measure the temperature of the slurry;
• and
• a step of controlling the temperature controller based on the temperature of the slurry measured by the temperature sensor.
