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: 7907597Abstract: An apparatus and method for seamlessly providing voice and data services to a user through an access terminal in a mobile communication system including a heterogeneous service & mobility gateway (HSMG) for an interworking service between a circuit network and a packet network, and various access networks overlapping each other. The access terminal notifies the HSMG that a voice call is received, if the access terminal that accessed a packet network receives a voice call. The HSMG sends a direction request to a circuit network upon receiving the notification indicating that the voice call is received. The access terminal directs to the circuit network and registers a new location upon receiving the direction request. The HSMG sets up an incoming voice call to the access terminal after the registration of a new location.Type: GrantFiled: August 26, 2004Date of Patent: March 15, 2011Assignee: Samsung Electronics Co., Ltd.Inventors: Sang-Do Lee, Jin-Man Kim, Tae-Won Kim, Hong-Sung Chang, Jae-Jeong Shim, Geun-Hwi Lim, Je-Hyun Jung

Patent number: 7260072Abstract: A data push service system and method using a heterogeneous network. The system transmits push data to a Hybrid Access Terminal (HAT) in a heterogeneous mobile communication system in which at least one circuit network overlaps with at least one packet network. The HAT can be connected to a circuit network or a packet network, and is registered in a new access network. The system includes a Packet Service & Mobility Gateway (PSMG) for acquiring access state and connection information of the HAT from the circuit network and the packet network, and generating an access network switching request upon receipt of an external request signal; and a Push Proxy Gateway (PPG) for acquiring access information of the HAT which will transmit the push data from the PSMG, and transmitting a request message to the PSMG.Type: GrantFiled: September 20, 2004Date of Patent: August 21, 2007Assignee: Samsung Electronics Co., Ltd.Inventors: Sang-Do Lee, Jin-Man Kim, Tae-won Kim, Young-Ki Jeon, Jin-Soo Lee, Soo-Hoi Kim, Jin-Seok Ko, Hong-Sung Chang, Sang-Jun Moon, Je-Hyun Jung

Publication number: 20070025298Abstract: A method and system for a roaming service in a mobile communication system are provided. The system includes an access terminal for transmitting an NAI (network access identifier) to a packet data serving node of the visited network and an AAA (authentication authorization accounting) of the home network, for transmitting subscriber profile information of the access terminal to the visited network. The packet data serving node of the visited network determines whether or not the access terminal subscribes to the roaming service on the basis of the NAI, and, when it is determined that the access terminal subscribes to the roaming service, sends a request for transmitting the subscriber profile information of the access terminal to the AAA of the home network. The packet data serving node of the visited network also provides at least one data service that the home network has provided to the subscriber, using the subscriber profile information.Type: ApplicationFiled: July 31, 2006Publication date: February 1, 2007Inventor: Je-Hyun Jung
