It is the thinnest compound known to man at one atom thick as well as the best known conductor. The supercapacitor consists of two layers of graphene with an electrolyte layer in the middle.

After much trial and error i figured out an excellent way to make graphene in quantities i could use to put on a film and them have rolled into a capacitor.

Graphene film capacitors. Capacitors on the other hand are able to be charged and release energy very quickly but can hold much less energy than a battery. The graphene sheets were produced by simple electrochemical exfoliation while the graphene films with controlled thickness were prepared by vacuum filtration. The film is strong exceedingly thin and is able to release a large amount of energy in a short.

S18 development of new film manufacturing processes optimization of device configuration. A supercapacitor sc also called an ultracapacitor is a high capacity capacitor with a capacitance value much higher than other capacitors but with lower voltage limits that bridges the gap between electrolytic capacitors and rechargeable batteriesit typically stores 10 to 100 times more energy per unit volume or mass than electrolytic capacitors can accept and deliver charge much. Improvement of graphene film electrodes such as film continuity and conductivity supplementary fig.

A supercapacitor 3v 12000 farads with electrodes in composite of graphene and activated carbon. Graphene capacitors are both highly flexible and have an energy density far beyond existing electrochemical capacitors possibly within reach of conventional lithium ion and nickel metal hydride. Graphene is a thin layer of pure carbon tightly packed and bonded together in a hexagonal honeycomb lattice.

Flexible graphene based thin film supercapacitors were made using carbon nanotube cnt films as current collectors and graphene films as electrodes. Graphene application developments though have lead to new possibilities for energy storage with high charge and discharge rates which can be made very cheaply. The capacitor in the battery is approximately 3500f rated at 22 to 38 volts.

Graphene based supercapacitors the company produced two new types of supercapacitors. It is widely regarded as a wonder material because it is endowed with an abundance of astonishing traits. Robust graphene composite films for multifunctional electrochemical capacitors with an ultrawide range of areal mass loading toward high rate frequency response and ultrahigh specific capacitance miao zhang xiaowen yu hongyun ma wencheng du liangti qu chun li gaoquan shi.

I paid a good deal of money to have a manufacturer create the capacitor using my graphene film.
