Abstract
An embodiment coating system for a secondary battery includes a supply tank connected to a slot-die and configured to store a slurry, an in-line viscometer configured to measure viscosity and temperature of the slurry, a flow meter configured to measure a flow rate of the slurry, a flow rate adjustment valve configured to adjust the flow rate according to a feedback signal based on the measured flow rate, a coating bead sensor configured to detect in real time a slurry coating bead shape discharged from the slot-die to a base material, and a coating controller configured to detect a process condition change event by monitoring a slurry property and the slurry coating bead shape in real time and to control the flow rate of the flow rate adjustment valve based on reference data corresponding to a changed slurry property.
