摘要： A device for coating an electrode slurry for a secondary battery and a method of coating an electrode slurry, which include a slurry transfer pipe with a dual structure including first and second pipes so that a temperature of the electrode slurry temperature can be kept constant when the electrode slurry stored in a slurry tank is transferred to a slot die. Accordingly, the electrode slurry is uniformly applied to a current collector so that a defective rate in electrode manufacturing can be reduced.
