The Science

By combining various metal oxides with graphene via our scalable, patent pending process, we aim to facilitate the next generation of supercapacitors, batteries and air purification systems by enhancing their constituent technologies.



The graph on the left shows the breakdown of an organic dye called methylene blue (to simulate organic pollutants in a fluid) by Anaphite and the leading market competitor photocatalyst (anatase TiO2). Methylene blue is a dye used in an ISO standard (ISO 10678) to help determine the activity of photocatalytic materials.

In this experiment performed by our scientists, the catalysts and the methylene blue were mixed and exposed to UV light for the time shown, after reaching absorption equilibrium in the dark overnight.

The rate constant of an exponential fit to the data for anatase was found to be 25 mins compared to that of Anaphite which was 8 mins - showing that Anaphite breaks down methylene blue 3X faster than anatase. As can be sen by the relative concentrations of methylene blue at 0 mins, the large initial absorbance from Anaphite shows the benefit of the additional surface area afforded by graphene.


Energy Storage

Incorporating graphene into certain materials can dramatically enhance their electrical properties, especially in the electrodes of energy storage devices. 

In the case of supercapacitors, by coating their electrodes with metal oxide-Graphene nanocomposites, over 5X specific capacitance increases have been achieved [1][2]. Since energy density is approximately proportional to specific capacitance, this leads to significant gains in energy storage capability.

In the case of Li-ion batteries by incorporating Graphene into metal oxide cathodes, power densities have been increased by up to 1.4X [3]. Metal oxides alone have shown a 2X increase in charging rates [4] and Graphene has the potential to improve this further.
