    • PROBLEM TO BE SOLVED: To provide a novel and simpler method of manufacturing a solid electrolytic capacitor having a low equivalent series resistance (ESR) and a low residual current without requiring the in situ polymerization, and capable of forming a solid electrolyte more stable against heat while protecting a dielectric against damage due to metal ions.SOLUTION: The manufacturing method of a solid electrolytic capacitor at least includes a) a step for applying a fluid dispersion A) containing at least the particles B) of a conductive polymer and a dispersant D) onto a porous body including a porous electrode body (2) of an electrode material and a dielectric (3) covering the surface of the electrode material, and b) a step for removing and/or hardening the dispersant D) at least partially in order to form a solid electrolyte (4) covering the dielectric surface completely or partially. Average diameter of the particles B) of a conductive polymer in the fluid dispersion A) is 1-100 nm, and the specific conductivity of a coating prepared from the particles B) is larger than 10 S/cm.
    • 要解决的问题:为了提供一种新颖而简单的制造具有低等效串联电阻(ESR)和低残留电流的固体电解电容器的方法,而不需要原位聚合,并且能够形成更多的固体电解质 在保护电介质免受金属离子损伤的同时,可以抵抗热量。 解决方案:固体电解电容器的制造方法至少包括a)将含有至少含有导电性聚合物和分散剂D)的粒子B)的流体分散体A)施加到包含多孔体 电极材料的电极体(2)和覆盖电极材料表面的电介质(3),以及b)至少部分地去除和/或硬化分散剂D)以形成固体电解质(4)的步骤 )完全或部分地覆盖电介质表面。 导电聚合物在流体分散体A)中的平均颗粒直径B)为1-100nm,由颗粒B)制备的涂层的比电导率大于10S / cm。 版权所有(C)2013,JPO&INPIT
