    • The present invention is directed to a conductive polyethylenedioxythiophene (PEDOT) polymer coated electrode adapted for use as a cathode electrode of an electrolytic capacitor and a method of manufacturing the same. According to the present invention, a metal foil substrate is placed in an aqueous solution of a doped 3,4-ethylenedioxythiophene (EDOT) monomer and a co-solvent, to dissolve the EDOT monomer, and a current is applied until the desired thickness of the polymer coating is electrochemically deposited. Additionally, an organic acid is added to the aqueous solution to act as an oxidizer. In order to improve the uniformity and adherence of the coating a surfactant may also be added. In a preferred embodiment, the EDOT monomer and cosolvent are first mixed, and then added to a water solution of oxidizer and dopant. The polymer film is deposited electrochemically onto the substrate by applying a DC current between 0.05 mA/cm2 and 5.0 mA/cm2 for 1 to 60 minutes, more preferably between about 0.13 mA/cm2 to about 0.26 mA/cm2 for between 9 and 18 minutes, such that a conductive polyethylenedioxythiophene (PEDOT) coating is formed on the electrode surface. According to the present invention, the increased surface area of the coated cathode results in lower gas generation and, therefore, reduced capacitor swelling, reduced oxide buildup on the cathode and prevention of electrolysis. The present invention results in electrodes with a minimum capacitance of 1 mF/cm2. The present invention also makes it possible to use thinner electrodes than conventional aluminum electrodes, thereby reducing the physical dimensions of the capacitor.
    • 本发明涉及适合用作电解电容器的阴极的导电聚亚乙基二氧噻吩(PEDOT)聚合物涂覆电极及其制造方法。 根据本发明,将金属箔基材置于掺杂的3,4-亚乙基二氧噻吩(EDOT)单体和助溶剂的水溶液中以溶解EDOT单体,并施加电流至所需厚度的 电化学沉积聚合物涂层。 另外,向水溶液中加入有机酸作为氧化剂。 为了提高涂层的均匀性和粘附性,还可以加入表面活性剂。 在优选的实施方案中,首先混合EDOT单体和共溶剂,然后加入到氧化剂和掺杂剂的水溶液中。 将聚合物膜通过在0.05mA / cm 2至5.0mA / cm 2之间施加DC电流1至60分钟,更优选在约 0.13mA / cm 2至约0.26mA / cm 2,持续9至18分钟,使得在电极表面上形成导电聚亚乙基二氧噻吩(PEDOT)涂层。 根据本发明,涂覆阴极的增加的表面积导致较低的气体产生,并因此降低电容器的膨胀,减少阴极上的氧化物积聚和防止电解。 本发明产生具有1mF / cm 2的最小电容的电极。 本发明还可以使用比常规铝电极更薄的电极,从而减小电容器的物理尺寸。
