Patent ID: 11476468

Abstract:
The present invention provides an electrode assembly, in which a plurality of electrodes are laminated, and a separator is inserted between adjacent electrodes. The outermost electrode disposed at an outermost layer of the electrode assembly includes a slurry applied to one surface of a current collector, and a protection layer adhered to the other surface of the current collector. Further, the outermost electrode is laminated to allow the slurry to contact the separator.Furthermore, a method for manufacturing the electrode assembly comprises applying a slurry to one surface of a current collector and laminating a protection layer on the other surface of the current collector to form an outermost electrode; allowing the outermost electrode to pass between a pair of press-rollers to perform a rolling process; and laminating the rolled outermost electrode to be disposed on an uppermost layer or a lowermost layer of the electrode assembly.
