Abstract
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.
