Abstract: Disclosed is a coating slurry supply device including an ultrasonic generator and a stirrer installed in a pipe configured to allow a slurry to be transferred therethrough. While the slurry is transferred through the pipe, a slurry additive containing a conductive material is dispersed and stirred. While being transferred through the pipe, the slurry does not stagnate in a specific section, thereby preventing slurry agglomeration caused by long-term mixing or dispersion. The slurry, the temperature of which increases due to heat generated during mixing or dispersion, is cooled through a cooling jacket, thereby appropriately adjusting the temperature so as to coat the slurry on a current collector or a support. This structure minimizes a change in physical properties of the slurry and maximizes dispersion of the slurry additive containing the conductive material.
