Patent number: 11916258Abstract: A secondary battery comprises an electrode assembly, a can, and an insulator. The electrode assembly includes a first electrode, a separator, and a second electrode alternately stacked and wound. The can has an accommodation part accommodating the electrode assembly therein, and the can comprises a first can and a second can having cylindrical shapes open in a direction facing each other. The insulator insulates an overlapping portion between the first can and the second can. The first can is electrically connected to the first electrode, and the second can is electrically connected to the second electrode. The insulator has a short-circuit induction through-part defined by a through-hole or a cutoff line, such that a short circuit occurs between the first can and the second can through the short-circuit induction through-part when it is deformed in shape as heat or a pressure is applied to contract or expand the insulator.Type: GrantFiled: October 4, 2019Date of Patent: February 27, 2024Assignee: LG Energy Solution, Ltd.Inventors: Gyung Soo Kang, Jee Ho Kim, Yong Tae Lee, Myung Hoon Ko, Jung Il Park, Ki Youn Kim

Patent number: 8431187Abstract: Disclosed herein is a method of producing a filter medium for treating medium and high temperature exhaust gas using foam coating and a filter medium produced using the method. The filter medium has excellent heat resistance and heat contraction resistance, and exhibits partial dust collection efficiency of 99% or more by weight, total dust collection efficiency of 99.999% or more by weight, and high dust removal efficiency, for all dust particle sizes. Further, the filter media can be efficiently used to treat medium and high temperature exhaust gas because pores having an average pore size of 30 ?m or less are uniformly distributed on the surface of the filter media.Type: GrantFiled: December 28, 2007Date of Patent: April 30, 2013Assignee: Korea Institute of Industrial TechnologyInventors: Gyung Soo Kim, Sang Bum Kim, Myong-Hwa Lee, Young-Chun Kim, Seung Je Lee, Byung Hyun Park
