Patent application numberDescriptionPublished
20080247118Nanoscale manganese oxide on ultraporous carbon nanoarchitecture - A composite comprising a porous carbon structure comprising a surface and pores and a coating on the surface comprising MnO10-09-2008
20080248192Electroless deposition of nanoscale manganese oxide on ultraporous carbon nanoarchitectures - A method of forming a composite comprising the steps of providing a porous carbon structure comprising a surface and pores and infiltrating the structure with a coating comprising MnO10-09-2008
20080292530CALCINATION OF CARBON NANOTUBE COMPOSITIONS - A carbon nanotube composition and method of making the same. The composition is made by: heating a precursor composition under a non-oxidizing or reducing atmosphere to form a carbon composition of carbon nanotubes and amorphous carbon; and calcining the carbon composition in the presence of oxygen to oxidize and vaporize the amorphous carbon without oxidizing the carbon nanotubes. The precursor composition includes a mixture or complex of a transition metal compound and an organic compound that chars at elevated temperatures.11-27-2008
20090092834RuO2-COATED FIBROUS INSULATOR - An article having: a nonconductive fiber and a RuO04-09-2009
20100176767Composite Electrode Structure - A method of forming a composite involving the steps of providing a porous carbon electrode structure having a surface and pores wherein the pores have an average diameter that ranges from about 2 nm to about 1 μm, depositing a coating comprising FeO07-15-2010
20100189991MACROPOROUS CARBON NANOFOAM COMPOSITES AND METHODS OF MAKING THE SAME - A method is disclosed to fabricate carbon foams comprising a bicontinuous network of disordered or irregular macropores that are three-dimensionally interconnected via nanoscopic carbon walls. The method accounts for (1) the importance of wetting (i.e., matching the surface energies of fiber to sol) and (2) the viscosity of the microheterogeneous fluid filling the voids in the carbon paper. Carbon fiber papers are mildly oxidized by plasma etching, which greatly enhances the uniform uptake of resorcinol-formaldehyde (RF) mixtures. The RF solutions are oligomerized prior to infiltration and are cured into continuous polymeric webs that hang supported between adjacent carbon fibers; the polymer-fiber composites are pyrolyzed and retain a sponge-like morphology with 10-1000-nm pores and integrated electronic pathways07-29-2010
20110027648Three-dimensional microbattery with tricontinuous components - A three-dimensional battery architecture device comprising a porous substrate that has an aperiodic or random sponge network that forms the scaffolding of the first electrode (either cathode or anode) of a battery, a first coating deposited on the porous substrate, wherein the first coating is an electron insulating, ion-conducting dielectric material, and a second coating deposited in the remaining free volume, wherein the second coating is a an interpenetrating electrically conductive material that forms the second electrode (respectively anode or cathode) of the battery. A method of making a three-dimensional battery architecture device comprising depositing a first coating on a porous substrate wherein the porous substrate has an aperiodic or random sponge network and wherein the first coating forms the electrolyte of the battery and depositing a second coating on the first coating, wherein the second coating is a an interpenetrating electrically conductive material that forms the second electrode of the battery.02-03-2011
20110037031CATION DEFICIENT MATERIALS FOR ELECTRICAL ENERGY STORAGE - A composition comprising: a metal oxide of a first metal ions and second metal ions; an electrically conductive material; and a binder material. The second metal ions have a higher oxidation state than the first metal ions. The presence of the second metal ion increases the number of metal cation vacancies. A method of: dissolving salts of a first metal ion and a second metal ion in water to form a solution; heating the solution to a temperature of about 80-90° C.; and adding a base to the solution to precipitate nanoparticles of a metal oxide of the first metal ion and the second metal ion.02-17-2011
20110091723RuO2 Coatings - Disclosed herein is an article having: a substrate and a RuO04-21-2011
