Electrode slurry coating method and apparatus comprising pressure adjustment member

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.
