본 고안은 전기 이중층 콘덴서에 관한 것으로서 보다 상세하게 설명하면, 다수의 절연지와 서로 절연된 분극선 전극을 권취하여 형성된 전기 이중층 콘덴서에서 콘덴서의 용량 확장을 위하여 결합되는 익스펜디드 메탈의 유연성 부족으로 인한 권취소자의 접착 불량과 밀봉 불량을 방지할 수 있고 용량을 확장시킬 수 있는 전기 이중층 콘덴서에 관한 것이다.The present invention relates to an electric double layer capacitor, which will be described in more detail. The electric double layer capacitor formed by winding a plurality of insulating papers and insulated polarization electrode electrodes is formed due to the lack of flexibility of expanded metal coupled to expand the capacity of the capacitor. The present invention relates to an electric double layer capacitor capable of preventing adhesion failure and sealing failure of a winding element and expanding its capacity.
일반적으로, 콘덴서는 전해액을 함유하는 전해 물질과 이들을 격리시켜 주는 절연 물질을 적층 및 권취하여 이를 절연시킨 후, 필름 상의 포장재를 포장하여 콘덴서를 형성한다.In general, a capacitor laminates and wound an electrolytic material containing an electrolyte and an insulating material that isolates them, insulates it, and then wraps a packaging material on a film to form a capacitor.
이와같은 콘덴서는, 다수의 전해지와 절연지를 권취하여 형성시킨 전해 콘덴서와, 전해지는 필름 상의 전해물질로 대용하여 사각형 형상으로 형성시킨 필름 콘덴서, 그리고 콘덴서의 용량을 향상시킨 전기 이중층 콘덴서 등으로 대별된다.Such capacitors are roughly classified into electrolytic capacitors formed by winding a large number of electrolytic cells and insulating papers, film capacitors formed into a rectangular shape by using an electrolytic material on a film, and electric double layer capacitors having improved capacities. .
여기에서, 전기 이중층 콘덴서는 다수의 집전 전극재와, 전해액이 함침되는 활성탄소 섬유(Actvated Carbon Fiber) 그리고 이들을 격리시키는 시퍼레이터와, 활성 탄소 섬유에 함침되는 전해액의 누출을 방지하는 개스킷으로 구성되는 단위 셀을 적층하여 인슐레이션 컵으로 절연시키며 여기에 음극 및 양극 리이드를 형성함과 아울러 콘덴서 케이스로 포밍(Forming)작업을 수행함으로써 완성된다.Here, the electric double layer capacitor is composed of a plurality of current collector electrode material, the activated carbon fiber impregnated with the electrolyte and the separator to isolate them, and the gasket to prevent leakage of the electrolyte impregnated in the activated carbon fiber The unit cells are stacked and insulated with an insulation cup, and the cathode and anode leads are formed thereon, and forming is performed by the capacitor case.
그러나, 다수의 활성 탄소 섬유와, 세퍼레이터 그리고 집전 전극재로 구성되어 있는 단위 셀을 적층하여 셀을 형성시키는 작업은, 다수의 전해지와 절연지를 상호적층시켜 이를 권취하는 공정에 비하여 복잡하며 생산성이 저하되고 이에 따라 제품의 원가가 상승되는 결점이 있었다.However, the work of stacking a unit cell composed of a plurality of activated carbon fibers, a separator, and a collecting electrode material to form a cell is more complicated than the process of laminating a plurality of electrolytic cells and insulating papers and winding them, and the productivity is lowered. As a result, the cost of the product increased.
이에 따라서, 생산 공정을 단순화하고, 생산 원가를 저하시키기 위하여 전기 이중층 콘덴서의 제조에 전해 콘덴서의 공정을 도입한 권취형 전기 이중층 콘덴서가 생산되었다.Accordingly, in order to simplify the production process and reduce the production cost, a wound type electric double layer capacitor has been produced in which the process of the electrolytic capacitor is introduced in the production of the electric double layer capacitor.
제3도는 종래 전기 이중층 콘덴서를 도시한 요부 개략 사시도로서, 세퍼레이터(A)를 개재하여 2개의 분극성 전극(B)이 상호 분리되어 설치되며, 상기 일측 분극성 전극의 후면에는 콘덴서의 용량확장을 위한 메쉬 형상의 익스펜디드 메탈(C)(Expended Metal)을 개재하여 이들의 절연을 위한 절연지(D)가 접착되어 권취토록 되며, 상기 권취된 분극성 전극(B)사이에는 리이드 단자(E)가 삽입되는 구조로 이루어진다.FIG. 3 is a schematic perspective view illustrating main parts of a conventional electric double layer capacitor, wherein two polarizable electrodes B are separated from each other through a separator A, and a capacitor is expanded on a rear surface of the one polarizable electrode. Insulating paper (D) for the insulation thereof is bonded to be wound through the expanded metal (C) (Expended Metal) of the mesh shape for the lead, and the lead terminal (E) between the wound polarized electrode (B) It is made of a structure that is inserted.
그러나, 이와같은 권취형 전기 이중층 콘덴서는, 각각의 단위 셀을 적층하여 형성한 전기 이중층 콘덴서에 비해 그 용량이 적어 대용량의 전기 이중층 콘덴서를 제작할 수 없을 뿐만 아니라, 익스펜디드 메탈(C)자체의 유연성이 부족하여 익스펜디드 메탈의 권취시, 탄성에 의해 권취소자의 밀봉성이 저하되고 각 소자의 접착 불량이 발생되는 문제점이 있었다.However, such a wound type electric double layer capacitor has a smaller capacity than the electric double layer capacitor formed by stacking each unit cell, and therefore, a large capacity electric double layer capacitor cannot be manufactured, and the expanded metal (C) itself When the expanded metal is wound due to lack of flexibility, the sealing property of the winding element is deteriorated due to elasticity, and there is a problem in that adhesion failure of each element occurs.
본 고안은 상술한 바와같은 종래의 여러 문제점들을 개선하기 위한 것으로 그 목적은, 각 소자가 권취되는 전기 이중층 콘덴서의 용량을 증가시킬 수 있도록 하여, 익스펜디드 메탈에 의한 권취소자의 접착 불량과 밀봉성 저하를 방지할 수 있는 전기 이중층 콘덴서를 제공하는데 있다.The present invention aims to improve various conventional problems as described above, and its purpose is to increase the capacity of the electric double layer capacitor in which each element is wound, so that the adhesion failure and sealing of the winding element by expanded metal It is to provide an electric double layer capacitor that can prevent degradation.
상기의 목적을 달성하기 위한 기술적인 구성으로서 본 고안은, 상하측 활성 탄소섬유 사이에 절연 세퍼레이터가 착설되며, 상기 상하측 활성 탄소 섬유 양측단부에는 밀폐를 위한 개스킷이 착설되고, 상기 상하 활성 탄소 섬유 표면에는 집전 전극재를 개재하여 절연 테이프로서 리이드 단자 일단이 결합되어 외부로 현출되는 단위셀을 적층 권선토록 한 구성으로 된 전기 이중층 콘덴서를 마련함에 의한다.As a technical configuration for achieving the above object, the present invention, an insulating separator is installed between the upper and lower activated carbon fibers, gaskets for sealing are installed at both ends of the upper and lower activated carbon fibers, the upper and lower activated carbon fibers An electric double layer capacitor having a structure in which one end of a lead terminal is coupled as an insulating tape to the outside by stacking winding unit cells through a current collector electrode material is stacked on the surface thereof.
