Gas injection nozzle for drying electrode plate and drying apparatus for electrode plate including the same

A drying apparatus for an electrode plate, the drying apparatus comprising:

• a chamber having a gas supply space through which drying gas for drying the electrode plate flows;
• and
• a plurality of gas injection nozzles coupled to the chamber to communicate with the gas supply space of the chamber,
• wherein the plurality of gas injection nozzles include:
• a nozzle body having a flow space through which drying gas flows, between a first plate and a second plate spaced apart from the first plate in a first direction;
• at least one inlet hole formed in the first plate and configured to allow the drying gas to flow into the flow space from the outside of the nozzle body;
• and
• a plurality of injection holes formed in the second plate and configured to inject the drying gas in the flow space to the outside,
• wherein the at least one inlet hole has a slit shape crossing the first plate in a second direction.

A drying apparatus for an electrode plate, the drying apparatus comprising:

• a chamber having a gas supply space and a plurality of gas injection nozzles in fluid communication with the gas supply space of the chamber through which drying gas for drying the electrode plate flows;
• wherein each of the plurality of gas injection nozzles includes:
• a nozzle body having a first plate and a second plate spaced apart from the first plate in a first direction;
• at least one inlet hole formed in the first plate and configured to allow the drying gas to flow into a flow space of the nozzle body from the gas supply space;
• a plurality of injection holes formed in the second plate and configured to inject the drying gas that is inside the flow space to an outside of the nozzle body, and
• a deflector disposed between the first plate and the second plate configured to change a flow direction of the drying gas entering the flow space through the at least one inlet hole before the drying gas is injected to the outside through the plurality of injection holes.
