First Graphene announces milestone on supercapacitor materials

First Graphene (FGR) has announced that it has reached a milestone on its program to develop high performing supercapacitor materials. FGR’s recent work has been focused on the development of an optimized bill of materials for a supercapacitor to deliver high energy and power densities.

First Graphene has now announced that, in a standard test cell, its product PureGRAPH hybrid active materials outperform leading activated carbon materials over 100 cycles. The PureGRAPH materials have a specific capacitance of 140 farads per gram (f/g) while activated carbon cells typically have a specific capacitance of 35 f/g. FGR said this shows that PureGRAPH hybrid active materials can be formulated into an electrode slurry for use in device manufacture.
