摘要： In the electrode assembly, the first uncoated portion provided at a long side end of a first electrode includes a segment region divided into a plurality of independently bendable segments by a plurality of cut grooves provided along a winding direction. The segment region includes a plurality of segment groups disposed with a group separation pitch along the winding direction. The plurality of segment groups constitute at least one segment alignment on one side of the electrode assembly. At least some of central points of winding turn arcs where the p number of segment groups are located are not located on a predetermined alignment line extending in the radial direction from the center of the core.

摘要： 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.
