Here, R 4 is H or a hydrocarbon group having 1 to 6 carbon atoms. At the same time, the present invention further discloses a capacitor polymer obtained by polymerizing the composition and a capacitor containing the capacitor polymer. The polymer obtained by polymerizing the composition provided by the present invention plays a role in repairing and protecting the oxide film on the metal foil, thereby significantly reducing damage to the oxide film on the capacitor metal foil.
Description
본 발명은 고체 상태 커패시터 재료 기술 분야에 관한 것으로, 더욱 상세하게는 조성물, 커패시터용 중합체 및 커패시터에 관한 것이다.The present invention relates to the field of solid state capacitor material technology, and more particularly to compositions, polymers for capacitors and capacitors.
고체 상태 전해 커패시터는 전도율이 높고 열안정성이 우수한 전도성 고분자를 전해질로 사용하여, 일반적인 액체 상태 커패시터에 비해 높은 신뢰성, 긴 사용 수명, 고주파의 낮은 임피던스, 초대형 리플 전류 내성 등의 특징을 가지고 있다. 또한 액체 상태 전해 커패시터 전해액이 액체가 누출되기 쉬운 단점을 극복하였다. 국내 전자 정보 산업이 급성장하면서 최근 몇 년간의 발전 추세에서 고체 상태 전해 커패시터가 점차 액체 상태 저전압 전해 커패시터를 대체하며 21세기 전자 정보 산업의 주류 제품 중 하나가 되고 있음을 알 수 있다.Solid-state electrolytic capacitors use conductive polymers with high conductivity and excellent thermal stability as electrolytes, and have features such as high reliability, long service life, low impedance at high frequencies, and ultra-large ripple current resistance compared to general liquid-state capacitors. In addition, the disadvantage of liquid electrolytic capacitor electrolyte, which is prone to liquid leakage, was overcome. With the rapid growth of the domestic electronic information industry, the development trend of recent years shows that solid-state electrolytic capacitors are gradually replacing liquid-state low-voltage electrolytic capacitors and are becoming one of the mainstream products of the 21st century electronic information industry.
사람들이 고체 상태 전해 커패시터 성능에 대한 요건이 증가함에 따라, 고전도성 고분자 커패시터에 내전압이 더욱 향상되고 누설 전류가 낮아져 커패시터 성능 및 사용 수명을 향상시키는 것은 연구원들의 공통 목표가 되었다. 알루미늄 전해 커패시터의 내전압은 산화알루미늄 산화막층의 두께에 비례하므로, 산화알루미늄 산화막층이 얇아지면 알루미늄박의 내전압이 낮아짐을 의미한다. 알루미늄박 산화막층 두께가 어느 정도까지 얇아지면, 양극박 내전압은 성능 요건을 충족하지 못하게 되며, 커패시터 사용 과정에서 양음극 도통, 소위 절연파괴(electrical breakdown) 현상이 발생한다. 부식이 상술한 가혹한 조건에 도달하지 않으면 누설 전류가 커질 수 있다. 누설 전류 크기 제어는 주요 고체 상태 알루미늄 전해 커패시터 제조업체가 제어해야 할 핵심이 되었다. 동시에, 최근 몇 년 동안 커패시터를 축소하려는 시장 수요 및 알루미늄 고체 상태 전해 커패시터 비용 절감에 대한 수요로 인해, 커패시터 제조업체에서 사용하는 양극박 내전압이 더욱 낮아지는 추세이다. 따라서 양극박의 부식을 완화시키고 커패시터 누설 전류 등 측면의 성능을 낮추기 위한 요건이 더욱 높아졌다.As people's requirements for solid-state electrolytic capacitor performance increase, it has become a common goal for researchers to provide high-conductivity polymer capacitors with further improved withstand voltage and lower leakage current to improve capacitor performance and service life. Since the withstand voltage of an aluminum electrolytic capacitor is proportional to the thickness of the aluminum oxide oxide film layer, this means that the withstand voltage of the aluminum foil decreases as the aluminum oxide oxide film layer becomes thinner. If the thickness of the aluminum foil oxide layer becomes thinner to a certain extent, the withstand voltage of the anode foil does not meet the performance requirements, and anode conduction, a so-called electrical breakdown phenomenon, occurs during the process of using a capacitor. If corrosion does not reach the severe conditions described above, the leakage current may become large. Leakage current magnitude control has become a key issue for major solid-state aluminum electrolytic capacitor manufacturers. At the same time, in recent years, due to the market demand for shrinking capacitors and the demand for reducing the cost of aluminum solid-state electrolytic capacitors, the withstand voltage of the anode foil used by capacitor manufacturers is trending lower. Therefore, the requirements to alleviate corrosion of the anode foil and reduce performance of aspects such as capacitor leakage current have increased.
현재, 고체 상태 알루미늄 전해 커패시터에는 3,4-에틸렌디옥시티오펜을 단량체로 사용하여 제조된 폴리-3,4-에틸렌디옥시티오펜(PEDOT) 중합체 재료가 일반적으로 사용된다. 상술한 중합체 재료는 우수한 도전성과 우수한 환경 안정성으로 인해 고체 상태 전해 커패시터 음극으로 널리 사용된다. 그러나 중합 반응에 사용되는 강산성 물질은 생성된 중합체 재료에 잔류할 수 있다. 커패시터 사용 시, 알루미늄박 산화막층을 부식시켜 이를 얇아지게 만들어 커패시터 내전압 강하 및 누설 전류 증가 문제를 야기할 수 있다. 따라서 단순히 3,4-에틸렌디옥시티오펜 단량체를 사용하여 제조된 고체 상태 알루미늄 전해 커패시터는 그 내전압 및 누설 전류 성능이 사람들의 증가하는 요건을 충족시킬 수 없다.Currently, poly-3,4-ethylenedioxythiophene (PEDOT) polymer material prepared using 3,4-ethylenedioxythiophene as a monomer is commonly used in solid-state aluminum electrolytic capacitors. The above-described polymer materials are widely used as solid-state electrolytic capacitor cathodes due to their excellent conductivity and excellent environmental stability. However, strongly acidic substances used in the polymerization reaction may remain in the resulting polymer material. When using a capacitor, the aluminum foil oxide layer can corrode and become thinner, causing problems such as a drop in the capacitor's withstand voltage and an increase in leakage current. Therefore, the solid-state aluminum electrolytic capacitor simply manufactured using 3,4-ethylenedioxythiophene monomer, its withstand voltage and leakage current performance cannot meet people's increasing requirements.

성능 테스트performance test
상기 실시예 1 내지 7 및 비교예 1 내지 4에서 제조된 고체 상태 전해 커패시터에 대해 다음과 같은 성능 테스트를 수행하였다.The following performance tests were performed on the solid-state electrolytic capacitors manufactured in Examples 1 to 7 and Comparative Examples 1 to 4.
자동 전자 부품 분석기 및 누설 전류 시험기를 이용하여 고체 상태 전해 커패시터의 정전용량, 손실값, 등가 직렬 저항 및 누설 전류를 시험한다. 여기에서 용량 및 손실값은 120Hz 주파수에서 시험하고, 등가 직렬 저항은 100KHz의 주파수에서 시험하며, 누설 전류는 정격전압으로 1min 동안 충전한 후 누설 전류 시험기로 시험한다. 시험 방법은 일반적인 자동 전자 부품 분석기와 누설 전류 시험기의 시험 방법으로, 여기에서 반복하여 설명하지 않는다.Test the capacitance, loss value, equivalent series resistance, and leakage current of solid-state electrolytic capacitors using an automatic electronic component analyzer and leakage current tester. Here, the capacity and loss values are tested at a frequency of 120Hz, the equivalent series resistance is tested at a frequency of 100KHz, and the leakage current is tested with a leakage current tester after charging at the rated voltage for 1 min. The test method is that of a general automatic electronic component analyzer and leakage current tester, and will not be repeated here.
테스트 결과는 표 1과 같다.The test results are shown in Table 1.
표 1 고체 상태 알루미늄 전해 커패시터 각 항목 성능 테스트 결과(16V680μF 코어)Table 1 Performance test results of each item of solid-state aluminum electrolytic capacitor (16V680μF core)
표 1의 시험 결과로부터 알 수 있듯이, 본 발명에서 제공하는 커패시터용 중합체로 제조된 고체 상태 전해 커패시터는 비교적 낮은 누설 전류값을 가지며, 최대가 7.3μA에 불과하다. 반면, 비교예 1 내지 4의 단량체로 제조된 고체 상태 전해 커패시터는 그 누설 전류값이 현저하게 크며 최소가 모두 12.5μA이다. 이는 인산 에스테르류 물질과 말단 캡핑제의 첨가가 고체 전해질의 알루미늄박에 대한 부식을 효과적으로 완화하며, 커패시터의 누설 전류를 낮추고 커패시터의 내전압 성능을 향상시켜 고체 상태 전해 커패시터의 성능 안정성을 보장하고 고체 상태 전해 커패시터의 사용 수명을 크게 향상시킬 수 있음을 설명한다.As can be seen from the test results in Table 1, the solid-state electrolytic capacitor made from the polymer for capacitors provided by the present invention has a relatively low leakage current value, with a maximum of only 7.3 μA. On the other hand, the solid-state electrolytic capacitors manufactured from the monomers of Comparative Examples 1 to 4 had significantly higher leakage current values, with a minimum of 12.5 μA. This means that the addition of phosphate ester-type materials and end capping agents effectively alleviates the corrosion of the aluminum foil in the solid electrolyte, lowers the leakage current of the capacitor and improves the withstand voltage performance of the capacitor, ensuring the performance stability of the solid-state electrolytic capacitor and solid-state electrolytic capacitor. It explains that the service life of electrolytic capacitors can be greatly improved.
비교예 1, 비교예 3 및 비교예 4의 시험 결과에서 알 수 있듯이, 인산 에스테르류 화합물과 말단 캡핑제는 모두 고체 전해질의 알루미늄박에 대한 부식을 완화하는 역할을 하며, 커패시터의 누설 전류를 낮춘다.As can be seen from the test results of Comparative Example 1, Comparative Example 3, and Comparative Example 4, both the phosphoric acid ester compound and the end capping agent play a role in alleviating corrosion of the aluminum foil of the solid electrolyte and lower the leakage current of the capacitor. .
