  • 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: 20240128517
    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.

  • Patent number: 10988527
    Abstract: The present invention relates to a method for preparing a TNFR-Fc fusion protein mixture comprising a target content of hydrophobic chromatogram peak 3, and to a method for adjusting a content of hydrophobic chromatogram peak 3. Specifically, the present invention relates to (a) a method for preparing a TNFR-Fc fusion protein mixture using a hydrophobic interaction chromatograph medium containing an aromatic functional group, which is pre-equilibrated with an equilibration buffer comprising sodium chloride or ammonium sulfate, and a sample comprising a TNFR-Fc fusion protein mixture liquid produced from mammalian cells, and to a method for adjusting the content of hydrophobic chromatogram peak 3 by hydrophobic chromatography using an equilibration buffer containing a predetermined concentration of sodium chloride or ammonium sulfate.
