SkeletonC Nanostructure

Tartu Technologies Ltd. in Tartu, Estonia, a research laboratory of Skeleton Group of Switzerland, has developed processing methods to control and manipulate the nanostructure and pore size distribution of carbide-derived carbon materials. Increased interest in carbon as a prospective material in electronics and several adsorption-based applications suggests that the methods and materials developed by researchers is ready for commercialization with interested partners.

Particular SkeletonC carbons have been especially designed for use in supercapacitors. These materials, due to their optimized pore size distribution and high bulk density, reach specific EDL (electric double layer) capacitance of ~100 Farads per cm3 in organic electrolytes. SkeletonC has assembled very high performance supercapacitors using the special carbon. The performance of the Skeleton technology device is significantly better in terms of both energy density (Wh/L) and power density (W/L) than commercially available devices. In fact, based on tests of a 1400F cell in his laboratory at the University of California-Davis, Dr. Andrew Burke has stated, “It is the best carbon/carbon cell we have ever tested in our laboratory.”

Testing of the 2.7V, 1400F device indicated an energy density of 7.6 Wh/L at a constant power discharge of 3.7 kW/L fully packaged. The capacitance and the energy stored in it were essentially constant for discharge powers between 375 and 3700W/L. The resistance of the device is 0.3 milliohms.

Tartu Technologies is a privately owned business which develops nanostructured carbon materials, including high performance material for supercapacitors.
