Publication number: 20240136674Abstract: 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.Type: ApplicationFiled: January 19, 2022Publication date: April 25, 2024Applicant: LG ENERGY SOLUTION, LTD.Inventors: Jong-Sik PARK, Jae-Won LIM, Yu-Sung CHOE, Hak-Kyun KIM, Je-Jun LEE, Byoung-Gu LEE, Duk-Hyun RYU, Kwan-Hee LEE, Jae-Eun LEE, Pil-Kyu PARK, Kwang-Su HWANGBO, Do-Gyun KIM, Geon-Woo MIN, Hae-Jin LIM, Min-Ki JO, Su-Ji CHOI, Bo-Hyun KANG, Jae-Woong KIM, Ji-Min JUNG, Jin-Hak KONG, Soon-O LEE, Kyu-Hyun CHOI

Publication number: 20240128517Abstract: 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.Type: ApplicationFiled: January 19, 2022Publication date: April 18, 2024Applicant: LG ENERGY SOLUTION, LTD.Inventors: Hae-Jin LIM, Jin-Hak KONG, Soon-O LEE, Kyu-Hyun CHOI, Do-Gyun KIM, Su-Ji CHOI, Kwang-Su HWANGBO, Geon-Woo MIN, Min-Ki JO, Jae-Won LIM, Hak-Kyun KIM, Je-Jun LEE, Ji-Min JUNG, Jae-Woong KIM, Jong-Sik PARK, Yu-Sung CHOE, Byoung-Gu LEE, Duk-Hyun RYU, Kwan-Hee LEE, Jae-Eun LEE, Bo-Hyun KANG, Pil-Kyu PARK

Patent number: 6843534Abstract: The present invention relates to an armrest apparatus installed in a chair for a computer work. An armrest member which is freely movable on a horizontal surface by a link apparatus is provided in an upper portion of an armrest body vertically installed at both sides of a seat of a chair. The armrest apparatus is used as a common armrest for a chair at a usual time on which a user's arms are placed in such a manner that an armrest member is closely contacted with an upper surface of an armrest body or is lifted upwardly. The armrest member is upwardly lifted at the height at which a keyboard work is conveniently performed during a computer work, so that a user's arms are freely movable on the armrest on a horizontal surface.Type: GrantFiled: June 17, 2002Date of Patent: January 18, 2005Inventors: Soon-won Lee, Jong-ho Lee
