Abstract

An apparatus and method of making the apparatus are provided having a plurality stacked undulating layers having an undulation pattern forming a patterned capacitor. At least one of the plurality of layers includes sublayers of dielectric material materials and electrically conducting materials.

First claim

1 . An apparatus comprising:
a plurality of sub-capacitors, at least one of which having an undulation or perforation pattern, wherein the apparatus forms a capacitor, and at least one of the plurality of sub-capacitors includes at least one sublayer of dielectric material and at least one electrically conducting material.

2 . The apparatus of claim 1 , wherein the undulation pattern or perforation pattern has an aspect ratio higher than 5 .

3 . The apparatus of claim 1 , wherein the undulation pattern has an RMS roughness of less than 100 microns.

4 . The apparatus of claim 1 , wherein an insulating layer is present between sublayers or sub-capacitors.

5 . The apparatus of claim 1 , wherein at least one dielectric material sublayer includes MXene material.

6 . The apparatus of claim 1 , wherein at least one dielectric material sublayer includes titanium dioxide material.

7 . The apparatus of claim 1 , wherein at least one dielectric material sublayer includes doped titanium dioxide material.

8 . The apparatus of claim 1 , wherein the distance between conducting layers is less than 20 microns.

9 . The apparatus of claim 1 , wherein the largest dimension is more than 1 mm.

10 . The apparatus of claim 1 , wherein the breakdown voltage is more than 1,000 volts.

11 . The apparatus of claim 1 , wherein the breakdown voltage is more than 5,000 volts.

12 . The apparatus of claim 1 , wherein the energy per volume is more than 1,000,000 Joules per cubic meter.

13 . The apparatus of claim 1 , wherein the at least one dielectric material sublayer includes a dielectric material with a dielectric constant higher than 100.

14 . The apparatus of claim 1 , further comprising boost or step down circuits configured to attach the apparatus to a vehicle or a consumer of electricity.

15 . The apparatus of claim 1 , further comprising attachments to transport the apparatus to an energy consumer.

16 . A method for manufacturing a patterned capacitor comprising
embossing layers of conductors and insulators, forming stacks of the layers via the sequential application of pressure, applied over a 3D printed shape-defined mold having an undulation pattern.

17 . An apparatus for manufacturing a patterned capacitor comprising:
at least one pressure controlled motorized embossing tool configured to press an embossing mold into a film surface for patterning films, wherein the apparatus is used to sequentially stack material films layer by layer for forming a capacitor.

18 . A method for manufacturing a patterned capacitor comprising:
assembling perforated conducting materials into sub-capacitors by successively and partially coating the perforated conducting materials with electrolyte and additional conducting materials, wherein the sub-capacitors are assembled into a capacitor.

19 . The method of claim 18 , wherein a perforated or sacrificial insulating or electrolytic layer is placed between the perforated conducting materials to stabilize the assembly during manufacturing.

20 . The method of claim 18 , wherein conducting edges of the sub-capacitors are on different locations of the sub-capacitors to enable assembly during manufacturing.
