摘要： There is provided a stacked and folded type electrode assembly in which at least two first electrode units having a first area and at least two second electrode units having a second area smaller than the first area are wound and stacked together with a rectangular separator. The electrode assembly includes: a first electrode stack in which the first electrode units are stacked; a second electrode stack in which the second electrode units are stacked; and a stepped portion formed by an area difference between the first electrode stack and the second electrode stack, wherein two or more layers of the separator cover the stepped portion, and the separator has the same shape as the stepped portion.

摘要： An electrode assembly includes at least one positive electrode coated with a positive electrode active material on both surfaces of a positive electrode current collector and at least one negative electrode coated with a negative electrode active material on both surfaces of a negative electrode current collector are alternately stacked in a direction perpendicular to a plane by placing a separation film therebetween. The electrode assembly includes a stepped part formed by placing a second electrode which has a different pole and a different area from those of a first electrode on the first electrode. At least one of outermost electrodes located on both surfaces of the electrode assembly is a one-side coated negative electrode, which has a surface coated with the negative electrode active material, and another surface as a non-coated portion. The non-coated portion is arranged in order to face the outside of the electrode assembly.
