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: 10726612Abstract: Provided is a method of reconstructing a three-dimensional (3D) model of an object. The method includes sequentially performing, by a camera module, first and second object scanning processes of scanning the same object, reconstructing, by a processor module, a 3D object model, based on a first object image obtained through the first object scanning process, performing pose learning on an object to generate learning data, based on data obtained through a process of reconstructing the 3D object model based on the first object image, and reconstructing, by the processor module, a final 3D object model, based on a second object image obtained through the second object scanning process and the learning data.Type: GrantFiled: August 17, 2018Date of Patent: July 28, 2020Assignee: Electronics and Telecommunications Research InstituteInventors: Byung Ok Han, Jae Hwan Kim, Ho Won Kim, Ji Hyung Lee, Yu Gu Jung, Chang Joon Park, Gil Haeng Lee
