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.

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.

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.

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 an axis to define a core and an outer circumference. The first electrode includes an uncoated portion at a long side end thereof and exposed out of the separator along a winding axis direction of the electrode assembly. A part of the uncoated portion is bent in a radial direction of the electrode assembly to form a bending surface region that includes overlapping layers of the uncoated portion, and in a partial region of the bending surface region, the number of stacked layers of the uncoated portion is 10 or more in the winding axis direction of the electrode assembly.

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 wound around a winding axis to define a core and an outer circumferential surface, the first electrode including a first uncoated region in which an active material layer is not coated along a winding direction; a housing accommodating the electrode assembly through an open portion at a lower end thereof; a first current collector coupled to the first uncoated region and disposed in the housing; a cap to cover the open portion; and a spacer between the first current collector and the cap and having a height corresponding to a distance between the first current collector and the cap.

Abstract: The present invention relates to a new use of lignan-type compounds or an extract of nutmeg or aril of nutmeg comprising the same. More particularly, the present invention relates to a composition for skin whitening comprising a lignan-type compound or an extract of nutmeg or aril of nutmeg comprising the same. Because the lignan compound represented by Chemical Formulas 1 to 3 or the extract of nutmeg or aril of nutmeg has superior skin whitening activity by inhibiting melanin production and tyrosinase activity, it can be used for the preparation of a cosmetic composition, food composition or pharmaceutical composition for skin whitening.

Abstract: The present invention relates to a novel use of lignan compounds, which are isolated and purified from nutmeg or the aril of nutmeg for anti-wrinkle, and more particularly, the present invention relates to a novel use for anti-wrinkle of an extract of the nutmeg or an extract of the aril of the nutmeg, fragrin A, austobailignan 7, licarin E, and macelignan. The extracts and lignan compounds of the present invention have activities in suppressing collagen degradation enzyme-1 (MMP-I, matrix metalloprotei-nase-1) and formation of new collagen (type-1 procollagen), thereby having effect on inhibitng wrinkle caused by photoaging. Accordingly, the extracts and lignan compounds of the present invention may be useful for preventing or treating wrinkle caused by photoaging.
