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.
Claims14
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.
