Publication number: 20190237811Abstract: Disclosed herein is a pouch-shaped secondary battery in which a unit cell, including an electrode assembly having a positive electrode and a negative electrode stacked with a separator interposed therebetween, electrode tabs, and electrode leads, is mounted in a pouch-shaped case, wherein the pouch-shaped secondary battery includes a unidirectional structure through which electrode leads oriented in two opposite directions are connected to electrode terminals oriented in a single direction. In the case in which a battery pack is constituted using a bidirectional cell, a large space is required, whereby the energy density of the battery pack is reduced. The lifespan of a unidirectional cell is reduced due to heat generated from electrode leads and due to nonuniform use of active materials in the cell at the time of charging and discharging the cell. The disclosed pouch-shaped secondary battery has the effect of solving the above problems.Type: ApplicationFiled: March 21, 2018Publication date: August 1, 2019Applicant: LG Chem, Ltd.Inventors: Jong Pil Park, Geun Chang Chung, Won Seok Jeong, Yo Han Ko

Patent number: 8146800Abstract: In an apparatus for recognizing a security code having an electromagnetic band gap (EBG) pattern which uses reflection and transmission characteristics of the EBG pattern, a voltage controlled oscillator generates a signal to a power divider, which divides the power of the signal into halves, and outputs a first signal through a waveguide to be incident on the EBG pattern. The waveguide receives a signal reflected from the EBG pattern and outputs the reflected signal to a phase detector. A circulator outputs the second signal to the phase detector, which detects the phase difference between the reflected signal and the second signal, and outputs phase difference data to a data control unit, which determines whether the security code having the EBG pattern is recognized using the phase difference data. In an alternate embodiment, the voltage control oscillator is controlled to sequentially generate signals using power difference data.Type: GrantFiled: June 4, 2010Date of Patent: April 3, 2012Assignee: Korea Minting, Security Printing & ID Card Operating Corp.Inventors: Jong Won Yu, Hyeong Seok Jang, Won Gyu Lim, Won Seok Jeong, Jin Ho Ryu, Hyun Mi Kim
