The electrode with layered graphene energy storage and dielectric layers may be used in a variety of electrolytic capacitor configurations.
Claims24
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;
- 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.

A method of making a capacitor, comprising the steps of:
- applying a layered graphene structure to a first current collector to form a first electrode with a dielectric layer;
- putting a separator adjacent the dielectric layer of the first electrode;
- putting a second electrode adjacent the separator, wherein the first electrode, separator, and second electrode define a layered stack;
- and
- impregnating the layered stack with an electrolyte.
2 more elements
An electrode for an electrolytic capacitor, comprising:
- a graphene dielectric comprised of at least one layer of a single layer graphene film;
