Description

복합전극의 구조를 갖는 전도성 고분자 콘덴서{Electrolyte condenser for having a compound electrode}A conductive polymer capacitor having a structure of a composite electrode {Electrolyte condenser for having a compound electrode}

본 발명은 전도성 고분자 콘덴서에 관한 것으로, 보다 상세하게는 전도성 고분자 콘덴서를 구성하는 양극포일과 음극포일의 사이에 활성탄층을 형성시켜 복합전극을 갖도록 하여 전도성 고분자 콘덴서의 용량을 증대시킬 수 있는 복합전극의 구조를 갖는 전도성 고분자 콘덴서에 관한 것이다.The present invention relates to a conductive polymer capacitor, and more particularly, a composite electrode capable of increasing the capacity of the conductive polymer capacitor by forming an activated carbon layer between the anode foil and the cathode foil constituting the conductive polymer capacitor to have a composite electrode. It relates to a conductive polymer capacitor having a structure of.

일반적으로 Al(알루미늄)의 전도성 고분자 콘덴서(condenser)는 Al포일(foil)을 전극으로 사용하여 대향되는 두 전극판 사이에 유전체 및 전해질을 개재시켜 직류전압을 인가하면 에너지(전하)를 축적하는 기능을 갖는다. 상기 Al 전도성 고분자 콘덴서는 Al 포일을 이용하여 제조되며, 에칭공정, 화성공정, 절단공정, 권취공정, 함침공정, 조립공정 및 재화성공정을 통해 Al 전도성 고분자 콘덴서가 제조된다. 즉, 상기 Al 전도성 고분자 콘덴서를 구성하는 양극포일(+)과 음극포일(-)의 사이에는 절연막이 삽설되어 Al 전도성 고분자 콘덴서를 구성하는 캔에 삽입된다. 상기 Al 전도성 고분자 콘덴서의 캔에 양극포일, 절연막, 및 음극포일을 함께 권취 및 삽입한 후 캔의 내부에 전해액을 주입하게 된다. 상기 전해액은 여러가지 화공약품을 조성해서 만든 액체로서 실질적인 음극역할을 한다.In general, a conductive polymer capacitor of Al (aluminum) uses Al foil as an electrode to accumulate energy (charge) when a DC voltage is applied through a dielectric and an electrolyte between two opposite electrode plates. Has The Al conductive polymer capacitor is manufactured using Al foil, and the Al conductive polymer capacitor is manufactured through an etching process, a chemical conversion process, a cutting process, a winding process, an impregnation process, an assembly process, and a regeneration process. That is, an insulating film is inserted between the positive electrode foil (+) and the negative electrode foil (−) constituting the Al conductive polymer capacitor and inserted into a can constituting the Al conductive polymer capacitor. After the positive electrode foil, the insulating film, and the negative electrode foil are wound and inserted together in the can of the Al conductive polymer capacitor, the electrolyte is injected into the can. The electrolyte is a liquid made by forming various chemicals and serves as a substantial cathode.

상기 전도성 고분자 콘덴서의 용량은 양극포일의 표면에 화성공정을 통해 형성된 유전체층과 음극포일의 표면에 자연적으로 형성되는 유전체층 및 양극포일과 음극포일의 사이에 주입되는 전해질에 의해 결정이 된다. 그런데 상기 양극포일의 표면에 형성되는 유전체층은 양극포일의 표면적에 비례하여 형성된다. 상기 유전체층의 형성된 양에 따라 전도성 고분자 콘덴서의 용량이 거의 결정되므로 유전체층이 많이 형성되면 콘덴서의 용량도 증가한다. 그러나 양극포일의 표면적이 한계가 있기 때문에 유전체층을 크게 형성시키지 못하여 전도성 고분자 콘덴서의 용량을 크게 증가시키지 못하는 문제점이 있다.The capacity of the conductive polymer capacitor is determined by a dielectric layer formed on the surface of the anode foil and a dielectric layer naturally formed on the surface of the cathode foil, and an electrolyte injected between the anode foil and the cathode foil. However, the dielectric layer formed on the surface of the anode foil is formed in proportion to the surface area of the anode foil. Since the capacitance of the conductive polymer capacitor is almost determined according to the amount of the dielectric layer formed, the capacitance of the capacitor also increases when many dielectric layers are formed. However, since the surface area of the anode foil is limited, there is a problem in that the dielectric layer cannot be formed largely and thus the capacity of the conductive polymer capacitor cannot be greatly increased.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 전도성 고분자 콘덴서를 구성하는 양극포일과 음극포일의 사이에 활성탄층을 형성시켜 복합전극을 갖도록 하여 전도성 고분자 콘덴서의 용량을 증대시킬 수 있는 복합전극의 구조를 갖는 전도성 고분자 콘덴서를 제공하는데 있다.The present invention has been made to solve the above problems, an object of the present invention is to form an active carbon layer between the anode foil and the cathode foil constituting the conductive polymer capacitor to have a composite electrode to increase the capacity of the conductive polymer capacitor It is to provide a conductive polymer capacitor having a structure of a composite electrode that can be increased.
