  • Patent number: 12249681
    Abstract: An electrode assembly, a battery, and a battery pack and a vehicle including the same are provided. One end of the electrode assembly includes a plurality of segment alignments in which the plurality of segment groups are aligned along a radial direction, and an electrolyte impregnation portion provided between segment alignments adjacent in a circumferential direction, wherein an end of the first active material portion is exposed between winding turns of the separator. The segments included in the segment alignment are bent toward the core to form a bending surface region. An end of the separator is spaced apart from a criterion line extending in a winding axis direction along a location corresponding to the plurality of cut grooves by 30% or less of a minimum height of the segments forming the bending surface region.

  • Patent number: 12230804
    Abstract: A method of manufacturing an all-solid-state battery electrode, an all-solid-state battery electrode manufactured by the method, and an all-solid-state battery including the electrode are disclosed. In the method, a specific type of binder included in the electrode is prepared in a fiber form by applying pressure to the binder under specific conditions, so that the fiber-form binder thus prepared has an average fineness that satisfies a specific range. Therefore, the all-solid-state battery including the electrode has an advantage of having high capacity even in the case of electrode thickening for high loading.
