Electrode Processing Device

Abstract

An electrode processing device includes an electrode cutting unit including a first cutter that cuts an electrode; and a deburring unit including a second cutter that cuts a burr protruding from the cut electrode cutting surface in a cutting direction of the first cutter. Also provided is an electrode assembly including an electrode and a separator, where at least one of the electrode and the separator is stacked and wound. The electrode includes a current collector and an electrode active material coated on an inner surface and an outer surface of the current collector. The electrode active material located on an outer surface of an end of the electrode has a higher density than an adjacent region.
