Electrolytic capacitor and method for manufacturing the same |
摘要 |
<p>The invention has an object to reduce the impedance and to improve the responsiveness at high frequencies in an electrolytic capacitor having an conducting polymer layer as the cathode. A cathode collector is directly joined with the surface of the dielectric of a valvular metal porous body for anode using an conducting polymer layer but not through various binding layers (for example, a carbon layer and a silver layer) thereby reducing the impedance. A cathode collector is disposed adjacent and opposite to a porous valvular metal foil for anode. This structure ensures that the collecting area is enlarged. In this case, a cathode collector may be directly joined with the surface of the dielectric of a valvular metal porous body for anode using an conducting polymer layer but not through various binding layers thereby reducing the total impedance. <IMAGE></p> |
