Abstract

A method of producing a super-capacitor provides a first substrate having a first base, forms a first electrode on the first substrate, and forms a separator so that the electrode is between the first base and the first separator. The method also micromachines holes through the separator, forms a chamber, and adds electrolyte, having ions, to the chamber. The electrolyte is in contact with the first electrode within the chamber. In addition, the holes are sized to permit transmission of the ions of the electrolyte through the holes.

First claim

What is claimed is:

1. A super-capacitor comprising:
a first substrate and a second substrate;
a first electrode supported by the first substrate;
a second electrode supported by the second substrate;
the first substrate bonded to the second substrate to form an interior chamber;
a first separator between the first electrode and the second electrode within the interior chamber, the first separator having a plurality of micromachined etch holes;
electrolyte, having ions, within the interior chamber and in contact with the first and second electrodes, the first separator micromachined etch holes being sized to permit the ions to pass through the micromachined etch holes.

2. The super-capacitor as defined by claim 1 wherein each of the first and second electrodes comprises a porous solid material.

3. The super-capacitor as defined by claim 2 wherein each of the first and second electrodes comprises a plurality of graphene monolayers.

4. The super-capacitor as defined by claim 1 further comprising a second separator between the first separator and the second electrode.

5. The super-capacitor as defined by claim 1 wherein the electrolyte comprises a cured gel electrolyte.

6. The super-capacitor as defined by claim 1 wherein the first separator comprises nitride or parylene.

7. The super-capacitor as defined by claim 1 wherein the first separator is formed from a material that is substantially ion impermeable to the ions within the electrolyte.

8. A super-capacitor comprising:
a first substrate and a second substrate that together form at least a portion of a die;
a first electrode and a second electrode, the first and second electrodes being spaced apart and being between the first and second substrates,
the die forming an interior chamber;
a separator between the first electrode and the second electrode within the interior chamber, the separator having a plurality of micromachined etch holes;
electrolyte, having ions, within the interior chamber and in contact with the first and second electrodes, the separator micromachined etch holes being sized to permit the ions to pass through the micromachined etch holes.

9. The super-capacitor as defined by claim 8 wherein each of the first and second electrodes comprises a porous solid material.

10. The super-capacitor as defined by claim 9 wherein each of the first and second electrodes comprises a plurality of graphene monolayers.

11. The super-capacitor as defined by claim 8 wherein the separator comprises a first separator and a second separator between the first and second electrodes.

12. The super-capacitor as defined by claim 8 wherein the electrolyte comprises a cured gel electrolyte.

13. The super-capacitor as defined by claim 8 wherein the separator comprises nitride or parylene.

14. The super-capacitor as defined by claim 8 wherein the separator is formed from a material that is substantially ion impermeable to the ions within the electrolyte.

15. A super-capacitor comprising:
a first substrate and a second substrate;
a first electrode and a second electrode, the first and second electrodes being spaced apart and positioned between the first and second substrates;
means for interior containing electrolyte between the first and second substrates;
means for separating the first electrode and the second electrode within the interior containing means;
electrolyte, having ions, within the interior containing means and in contact with the first and second electrodes, the separating means having micromachined etched means for permitting the ions to pass through the separating means.

16. The super-capacitor as defined by claim 15 wherein the permitting means comprises a plurality of micromachined etch holes through the separating means.

17. The super-capacitor as defined by claim 15 wherein each of the first and second electrodes comprises a porous solid material.

18. The super-capacitor as defined by claim 17 wherein each of the first and second electrodes comprises a plurality of graphene monolayers.

19. The super-capacitor as defined by claim 15 wherein the electrolyte comprises a cured gel electrolyte.
