Abstract
An electrode assembly includes an anode; a cathode; and a separator between the anode and the cathode rolled together. The anode includes an anode current collector and an anode active material portion applied onto the anode current collector, and the cathode includes a cathode current collector and a cathode active material portion applied onto the cathode current collector. An anode uncoated portion of the anode current collector at which the anode active material is not applied extends in a first direction, and a cathode uncoated portion of the cathode current collector at which the cathode active material is not applied extends in an opposite direction. The cathode active material portion includes a loading reduction portion in which a loading amount of the cathode active material is smaller than that of an adjacent region. The loading reduction portion is at one end part of the cathode in the first direction.
