Abstract: Provided are an electrode assembly, a battery, and a battery pack and vehicle including the same. An electrode assembly, in which a first electrode, a second electrode, and a separator interposed therebetween are wound about an axis to define a core and an outer circumferential surface. At least one of the first electrode and the second electrode includes, at a long side end portion, an uncoated portion exposed beyond the separator in a direction of the axis. At least a part of the uncoated portion is bent in a radial direction of the electrode assembly to define a bent surface region having overlapping layers of the uncoated portion. The bent surface region includes a welding target region having a number of the overlapping layers of the uncoated portion, and the welding target region extends along a radial direction of the electrode assembly.
