Flow rate control apparatus and method for coating multi-division dual layers

Abstract

A flow rate control apparatus for coating multi-division dual layers, including a plurality of slot dies organized into an upper layer and a lower layer, and configured to coat an electrode with a slurry; a pump configured to supply the slurry from a tank to each of the upper layer and the lower layer; a valve at the plurality of slot dies, and configured to divide the slurry supplied from the pump, and to supply the divided slurry to the plurality of slot dies; a flowmeter configured to measure a flow rate of the slurry supplied to the plurality of slot dies; and a processor configured to control the pump and the valve based on the flow rate of the slurry measured by the flowmeter to control a coating amount of the electrode.
