Lomiko Metals Inc. (TSXV:LMR,FWB:DH8B) announced the successful conversion of flake graphite from the Quatre Milles property, as tested at Graphene Laboratories Inc. Graphite samples were converted to Graphene Oxide and Reduced Graphene Oxide.
As quoted in the press release:
In the first step of the conversion process the natural graphite flakes were oxidized and turned into GO by modified Hummer’s method. As the result, a stable aqueous dispersion with concentration of 40 g/L was obtained. Further, the GO was converted into RGO. The specific surface area of the RGO was found to be 500 m2/g and its electrical conductivity 4 S/cm. These values are similar or exceeding the values for the RGO obtained from other samples of natural graphite taken for comparison and processed by the same procedure. The RGO samples will be used further for preparation of a supercapacitor prototype and samples of graphene-base composite material for further testing.
“Quality of graphene materials strongly depend upon quality of the starting material, graphite. We are greatly pleased with results of testing of Lomiko’s mineral samples and looking forward using of this material in our R&D program as well as production. We hope to use Quatre Milles graphite to reduce costs and create new product lines” stated Elena Polyakova, CEO of Graphene Labs.
Lomiko Metals CEO, A. Paul Gill, said:
One of the barriers to widespread use of graphene is the cost of producing it in useable forms. By confirming that graphene may be easily created from natural flake graphite, Graphene Labs and Lomiko hope to produce the material on a larger scale and at a reduced price.
