ELECTRODE SLURRY CONTROL DEVICE

The present specification relates to an electrode slurry control device including a main body having a receiving port configured to receive electrode slurry from an outside storage, a coater configured to discharge electrode slurry onto a substrate, a supply tube configured to supply the electrode slurry in the main body to the coater and connected to the main body through a first connection tube having a first opening/closing member, a first circulation tube configured to move a part of the electrode slurry introduced into the main body to the storage, the first circulation tube being connected to the main body through a second connection tube having a second opening/closing member; and a second circulation tube configured to move a part of the electrode slurry in the main body to the storage and connected to the main body through a third connection tube having a third opening/closing member, in which an average diameter of an inner peripheral surface of the second connection tube is smaller than an average diameter of an inner peripheral surface of the first circulation tube, and in which an average diameter of an inner peripheral surface of the third connection tube is larger than an average diameter of an inner peripheral surface of the second connection tube.
