Contact ORNL About This Technology



Technology Marketing SummaryCurrent supercapacitor technologies cannot meet the growing demands for high-power energy storage. Meeting this challenge requires the development of new electrode materials.DescriptionScientists at ORNL have developed robust carbon monolithic having hierarchical porosity characterized by macropores and mesopores. The macropores have a size in the range of 0.05 microns to 100 microns and the mesopores have a range from 18 Angstroms to 50 nanometers. These structures mean a high surface area carbon adsorbent resulting in greater levels of charge storage capabilities compared to other commercially available carbon based electrode materials. Thus; the mega-pored nano-structured carbon is a promising material for supercapacitor electrodes with superior power and energy performance.Benefits
  • High surface area carbon adsorbent
  • Ability to functionalize carbon
  • Excellent electrical conductivity, corrosion resistant, high temperature stability
  • Percolated pore structure, chemical and mechanical stability
  • Carbon monolithic structure permits the achievement of high permeability and fast mass transfer kinetics
Applications and Industries

Highly ordered porous carbon materials having well defined nanostructures and method of synthesis
Applicant's present invention comprises a method for fabricating porous carbon materials having highly ordered nanostructures comprising the steps of first, forming a precursor solution comprising a block copolymer template and a carbon precursor; second, forming a self-assembled nanostructured material from the precursor solution; third annealing the nanostructured material thereby forming a highly ordered nanostructured material; fourth, polymerizing the carbon precursor to cure the nanostructured material; and pyrolyzing the nanostructured material wherein the block copolymer template is decomposed to generate ordered carbon nanopores and the nanostructured material is carbonized to form the walls of the carbon nanopores thereby forming a porous carbon material having a highly ordered nanostructure. In addition, the present invention further comprises a porous carbon material comprising a carbon nanostructure having ordered carbon nanopores that have uniform pore sizes ranging from about 4.5 nm up to about 100 nm.
