Abstract
An electrode assembly having a first electrode, a second electrode, and a separator interposed therebetween are wound, and the first electrode includes an insulation layer that covers a boundary of an uncoated portion and a coated portion along a winding direction of the electrode assembly. A plurality of segments are bent along a radial direction of the electrode assembly to define a bent surface. When a line parallel with the winding direction and passing through a point corresponding to a segment having a smallest height in the region of the uncoated portion of the first electrode is a datum line and the segment with the smallest height among the segments defining the bent surface is a minimum segment, a separation distance between an end of the separator and the datum line along the winding axis is 30% or less of the smallest height of the minimum segment.
