摘要： Disclosed is an electrode assembly, a battery, and a battery pack and a vehicle including the same. In the electrode assembly, a first electrode, a second electrode, and a separator interposed therebetween are wound based on a winding axis to define a core and an outer circumference. The first electrode includes a first active material portion coated with an active material layer and a first uncoated portion not coated with an active material layer along a winding direction. At least a part of the first uncoated portion is defined as an electrode tab by itself. The first uncoated portion includes a first portion adjacent to the core of the electrode assembly, a second portion adjacent to the outer circumference of the electrode assembly, and a third portion interposed between the first portion and the second portion. The first portion or the second portion has a smaller height than the third portion in the winding axis direction.

摘要： 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.
