Abstract
An electrode assembly, a battery, and a battery pack and a vehicle including the same are provided. One end of the electrode assembly includes a plurality of segment alignments in which the plurality of segment groups are aligned along a radial direction, and an electrolyte impregnation portion provided between segment alignments adjacent in a circumferential direction, wherein an end of the first active material portion is exposed between winding turns of the separator. The segments included in the segment alignment are bent toward the core to form a bending surface region. An end of the separator is spaced apart from a criterion line extending in a winding axis direction along a location corresponding to the plurality of cut grooves by 30% or less of a minimum height of the segments forming the bending surface region.
