Abstract
A process for preparing a solid electrolytic capacitor comprising application of a non-ionic polyol prior to application of a conducting polymer layer.
Claims21
A method of forming an electrolytic capacitor comprising:
- providing an anode with an anode lead extending therefrom;
- forming a dielectric on said anode;
- forming a conductive polymer layer on said layer of dielectric;
- forming a layer of non-ionic polyol on said conductive polymer layer;
- and
- forming a second conductive polymer layer on said layer of non-ionic polyol.
