## Abstract

Improvements in design and manufacturing techniques to produce a graphene based prismatic supercapacitor of very high capacitance with very high energy density storage able to outperform and replace the cutting edge batteries available in the market today.

## Claims

### Claim 1

A manufacturing process for the production of supercapacitors having increased energy density, comprising:
perforating a series of orifices on an element sheet;
layering the element sheet with photoresist on one or both sides;
exposing portions of the photoresist to a light source to remove these portions from the element sheet;
printing graphene ink within the remaining portions of the photoresist and through the orifices;
printing graphene ink on both sides of the element sheet filling the orifices to create terminals that have a larger size as compared to the remaining portions and to connect both sides of the element sheet;
removing remaining portions of photoresist thereby leaving a pattern design; printing electrolyte within the pattern design; and
wherein the pattern design forming electrodes having minimal spacing between gaps to increase the energy density within the supercapacitor.

### Claim 2 (depends on 1)

The manufacturing process for the production of supercapacitors of claim 1 wherein the minimal gaps between the printed electrodes is less than five microns.

### Claim 3 (depends on 1)

The manufacturing process for the production of supercapacitors of claim 1 wherein the minimal gaps between the printed electrodes is between one hundred nanometers to two microns.

### Claim 4 (depends on 1)

The manufacturing process for the production of supercapacitors of claim 1 comprising increasing the thickness of the photoresist to increase the depth of the graphene ink layer and the electrolyte layer thereby increasing the energy density of the supercapacitor.

### Claim 9 (depends on 1)

The manufacturing process for the production of supercapacitors of claim 1 comprising individual capacitors connected in series.

### Claim 10 (depends on 1)

The manufacturing process for the production of supercapacitors of claim 1 comprising individual capacitors connected in series and parallel.

### Claim 11 (depends on 1)

The manufacturing process for the production of supercapacitors of claim 1 comprising a pattern design comprising individual fringes of the electrode terminating in a curved end with a matching curved contour on an adjacent electrode.

### Claim 12 (depends on 1)

The manufacturing process for the production of supercapacitors of claim 1 comprising stacking element sheets in parallel to increase the capacitance and the current of the supercapacitor.

### Claim 13 (depends on 1)
