Patent ID: 11322799

Abstract:
The present invention provides an electrode assembly in which a plurality of unit cells are disposed, wherein one of the unit cells comprises: a first double-sided electrode in which a slurry is on opposite surfaces of a first collector; a separator adjacent to the first double-sided electrode; a second double-sided electrode adjacent to the separator and in which a slurry is on opposite surfaces of a second collector; and a single-sided electrode adjacent to the second double-sided electrode and in which the slurry is only on one surface of a third collector, the one surface facing the second double-sided electrode, the single-sided electrode having a coating layer on the slurry thereof, the coating layer preventing contact between the slurry of the single-sided electrode and the slurry on one of the surfaces of the second collector that faces the single-sided electrode, the coating layer allowing ions to pass therethrough.
