Patent number: 9397373Abstract: A lithium ion secondary battery including a compound containing at least one thiol group (—SH) in a molecule in a unit cell of the battery is provided. By including the compound containing thiol group (—SH) having good reactivity with copper or copper ions, the formation of dendrite through the reduction of copper ions present in the inner portion of the battery or produced during operating the battery at the surface of an anode may be prevented. The internal short between two electrodes due to the dendrite may be also prevented.Type: GrantFiled: January 7, 2014Date of Patent: July 19, 2016Assignee: LG Chem, Ltd.Inventors: Sung Joon Park, Seung Don Choi, Ho Jin Jeon, Dae Sik Choi, You Rim Yoon, Chang Moon Jeong, Jae Sik Yoon, Yong Pal Park

Patent number: 9142825Abstract: Provided are an electrode lead of a secondary battery where a protection layer for anti-corrosion is selectively formed at an electrode lead portion at the cell outside and a secondary battery including the same. Since a protection layer for anti-corrosion is selectively formed only on an electrode lead portion at the cell outside, the corrosion of the electrode lead may be prevented from an external environment and the resistance of a cell may be reduced simultaneously.Type: GrantFiled: January 18, 2012Date of Patent: September 22, 2015Assignee: LG Chem, Ltd.Inventors: Seung Su Cho, Seung Don Choi, Ho Jin Jeon, Dae Sik Choi, Dae Hong Kwon, You Rim Yoon

Publication number: 20120040235Abstract: Provided are a pouch-type secondary battery having improved safety, and a battery pack including the pouch-type secondary battery. When inner pressure of a pouch is increased by an overdischarge, the pouch is deformed to separate electrode leads from electrode tabs. When the secondary battery is manufactured, an additional material or device is unnecessary. In addition, since the pouch-type secondary battery fundamentally cuts off electric current when gas is generated therein, the service life and safety of the secondary battery can be significantly improved, and the manufacturing costs and the weight thereof can be reduced. Furthermore, the shape of the secondary battery can be easily modified.Type: ApplicationFiled: September 23, 2011Publication date: February 16, 2012Applicant: LG CHEM, LTD.Inventors: Seung Su CHO, You Rim YOON, Seung Don CHOI, Ho Jin JEON, Dae Sik CHOI, Dae Hong KWON
