1. An apparatus for coating an electrode slurry, comprising:
an electrode slurry discharge flow path configured to discharge an electrode slurry through a slit formed on an interface between first and second dies;
an electrode slurry storage tank configured to be fluidly connectable to the electrode slurry discharge flow path and store the electrode slurry therein at a static pressure condition; and
a static pressure opening and closing valve configured to be located on a flow path on which the electrode slurry discharge flow path is fluidly connected to the electrode slurry storage tank,
wherein an opening or closing of the static pressure opening and closing valve is determined according to a difference between a pressure of the electrode slurry discharge flow path and an internal pressure of the electrode slurry storage tank,
wherein the electrode slurry discharge flow path and the electrode slurry storage tank face each other, and are directly connected, in a state in which the static pressure opening and closing valve is interposed therebetween.
