Abstract
The disclosure describes an improved electrolytic capacitor, more specifically, an electrolytic capacitor with a graphene-based energy storage layer and dielectric, and a method of making the improved electrolytic capacitor. The electrode with layered graphene energy storage and dielectric layers may be used in a variety of electrolytic capacitor configurations.
Claims18
A capacitor, comprising:
- a first electrode comprised of a first current collector and a dielectric disposed adjacent the current collector, wherein the dielectric comprises a layered graphene structure;
- a second electrode comprised of a second current collector and a graphene energy storage layer;
- a separator disposed between the first electrode and the second electrode;
- and
- an electrolyte impregnated between the first electrode and the separator and between the second electrode and the separator.
