ELECTRODE ASSEMBLY AND METHOD FOR MANUFACTURING SAME

An electrode assembly according to an embodiment of the present disclosure includes an anode; a cathode; and a separator disposed between the anode and the cathode, wherein the anode, the cathode and the separator are rolled together to form a j elly-roll structure, wherein the anode includes an anode current collector and an anode active material portion formed by applying an anode active material onto the anode current collector, wherein the cathode includes a cathode current collector and a cathode active material portion formed by applying a cathode active material onto the cathode current collector, wherein an anode uncoated portion, to which the anode active material is not applied among the anode current collector, extends in a first direction, wherein a cathode uncoated portion, to which the cathode active material is not applied among the cathode current collector, extends in a second direction opposite to the first direction, wherein the cathode active material portion includes a loading reduction portion in which the loading amount of the cathode active material is smaller than that of the adjacent region, and wherein the loading reduction portion is disposed at one end part of the cathode in the first direction.
