  • Publication number: 20240136674
    Abstract: 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.

  • Publication number: 20240136664
    Abstract: A battery includes an electrode assembly including a first electrode, a second electrode and a separator between the first electrode and the second electrode, the first electrode, the second electrode and the separator being wound around a winding axis to define a core and an outer peripheral surface. The first electrode and the second electrode include a first uncoated region and a second uncoated region along a winding direction, respectively, and an active material layer coating is absent in the first uncoated region and the second uncoated region. The battery further includes a housing receiving the electrode assembly through an opening formed at a bottom, a first current collector coupled to the first uncoated region and disposed within the housing, a cap covering the opening, a spacer interposed between the cap and the electrode assembly to fix the electrode assembly and seal the housing, and a terminal electrically connected to the second uncoated region.

  • Publication number: 20240128605
    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.
