摘要： An electrode assembly, a battery, and a battery pack and a vehicle including the same are provided. In the electrode assembly, a first electrode, a second electrode, and a separator interposed therebetween are wound based on an axis to define a core and an outer circumference. The first electrode includes a first portion coated with an active material and a second portion at a first side and adjacent the first portion, the second portion being exposed beyond the separator along a first axial direction of the electrode assembly. A part of the second portion is bent in a radial direction of the electrode assembly forming a first surface region including stacked layers of the second portion, and in a partial region of the first surface region, a number of the stacked layers of the second portion is 10 or more in the in the first axial direction.

摘要： An electrode assembly, a battery, a battery pack and a vehicle including the same are provided. In the electrode assembly, the uncoated portion of an electrode includes a segment region divided into a plurality of segments, and the segment region includes a plurality of segment groups separated by a group separation pitch along a winding direction. One end of the electrode assembly includes a plurality of segment alignments. In winding turns corresponding to the plurality of segment alignments, group separation pitches of segment groups disposed in a same winding turn are substantially identical, and separation pitches of the segment groups is greater in a winding turn of a region adjacent to the outer circumference of the electrode assembly than in a winding turn of a region adjacent to the core of the electrode assembly.
