Abstract
A slot die includes: an upper die; a lower die having a cavity, a gap being formed between the upper die and the lower; a slurry supply unit connected to an external slurry supply source, the cavity being connected to the slurry supply unit; a temperature controller adjacent to the cavity and configured to control a temperature of a slurry in the cavity; and a temperature sensor configured to measure the temperature of the slurry. A slot is formed by the gap, is connected to the cavity, and is configured to emit the slurry onto a base material.
