Graphene Laboratories logoLomiko Metals logoGraphene Laboratories announced that they have successfully managed to convert Lomiko Metal's Quatre Milles property graphite to graphene. They have actually produced graphene oxide (GO) and reduced graphene oxide (RGO) samples. The companies hope that they will be able to create graphene materials on a larger scale and at a reduced price.

In the first step of the conversion process the natural graphite flakes were oxidized and turned into GO by modified Hummer's method. This resulted in a stable aqueous dispersion with concentration of 40 g/L. The GO was then converted into RGO, with a surface area of 500 m2 /g and an electrical conductivity 4 S/cm.

The companies will now attempt to use the RGO samples to build a supercapacitor prototype. This project is being done in collaboration with the SUNY Research Foundation at Stony Brook University.

Here's an interview with Lomiko Metal's CEO discussing their agreement with Graphene Labs:
