Abstract
The disclosure describes an improved electrolytic capacitor, more specifically, a method of making an electrolytic capacitor with a graphene-based energy storage layer and dielectric. The electrode with layered graphene energy storage and dielectric layers may be used in a variety of electrolytic capacitor configurations.
Claims14
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, wherein the dielectric layer is formed of at least one film layer of the layered graphene structure;
- 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.
