Abstract: A solid electrolytic capacitor that contains an anode body formed from an electrically conductive powder and a dielectric coating located over and/or within the anode body is provided. The present inventors have discovered a technique that is believed to substantially improve the uniformity and consistency of the manganese oxide layer. This is accomplished, in part, through the use of a dispersant in the precursor solution that helps minimize the likelihood that the manganese oxide precursor will form droplets upon contacting the surface of the dielectric. Instead, the precursor solution can be better dispersed so that the resulting manganese oxide has a “film-like” configuration and coats at least a portion of the anode in a substantially uniform manner. This improves the quality of the resulting oxide as well as its surface coverage, and thereby enhances the electrical performance of the capacitor.

Abstract: An electrode for a supercapacitor includes a block copolymer and active material particles. The block copolymer is used both to bind the particles together and to act as an electrolyte. The electrode does not have a porous structure, but rather it is pressed or rolled to achieve zero porosity and to ensure good contact between the particles and the block copolymer electrolyte. Thus, the entire surface of the active particles can be accessed for charge storage. Furthermore, the volume of such an electrode is smaller than typical electrodes with the same capacity, as none of the volume is wasted with additional, non-active binder material, offering a higher effective active material loading per unit volume. Electrodes made in this way, with block copolymer electrolyte and active materials, can also form free-standing films that are easy to handle during manufacture of supercapacitors.
