Publication number: 20240136664Abstract: 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.Type: ApplicationFiled: February 18, 2022Publication date: April 25, 2024Applicant: LG ENERGY SOLUTION, LTD.Inventors: Min-Ki JO, Bo-Hyun KANG, Do-Gyun KIM, Su-Ji CHOI, Kwang-Su HWANGBO, Hae-Jin LIM, Jae-Won LIM, Hak-Kyun KIM, Je-Jun LEE, Ji-Min JUNG, Geon-Woo MIN, Jae-Woong KIM

Publication number: 20240128605Abstract: 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.Type: ApplicationFiled: February 18, 2022Publication date: April 18, 2024Applicant: LG ENERGY SOLUTION, LTD.Inventors: Min-Woo KIM, Do-Gyun KIM, Kyung-Wook CHO, Geon-Woo MIN, Min-Ki JO, Jae-Woong KIM, Kwang-Su HWANGBO, Hae-Jin LIM, Su-Ji CHOI, Jae-Won LIM, Hak-Kyun KIM, Je-Jun LEE, Ji-Min JUNG
