20080206484 | Graphitized Carbon Coatings for Composite Electrodes - A method for forming a graphitic carbon film at low temperatures is described. The method involves using microwave radiation to produce a neutral gas plasma in a reactor cell. At least one carbon precursor material in the reactor cell forms a graphitic carbon film on a substrate in the cell under influence of the plasma. This method can be used to coat active electrode material powders with highly conductive carbon, which can be especially useful in forming composite electrodes. When an organometallic is used as the precursor, this method can also be used to form carbon/metal catalyst films. | 08-28-2008 |
20090183650 | OPTIMIZATION OF CARBON COATINGS - Several synthetic additives have been used to improve the carbon coatings on LiFePO4 electrode materials. Pyromellitic acid (PA) added prior to calcination decreases the D/G ratios of the carbon produced in situ, while the use of both iron nitrate and PA results in increased sp | 07-23-2009 |
20100055441 | MICROWAVE PLASMA CVD OF NANO STRUCTURED TIN/CARBON COMPOSITES - A method for forming a graphitic tin-carbon composite at low temperatures is described. The method involves using microwave radiation to produce a neutral gas plasma in a reactor cell. At least one organo tin precursor material in the reactor cell forms a tin-carbon film on a supporting substrate disposed in the cell under influence of the plasma. The three dimensional carbon matrix material with embedded tin nanoparticles can be used as an electrode in lithium-ion batteries. | 03-04-2010 |
20100175745 | SURFACE PLASMON-ENHANCED PHOTOVOLTAIC DEVICE - Photovoltaic devices are driven by intense photoemission of “hot” electrons from a suitable nanostructured metal. The metal should be an electron source with surface plasmon resonance within the visible and near-visible spectrum range (near IR to near UV (about 300 to 1000 nm)). Suitable metals include silver, gold, copper and alloys of silver, gold and copper with each other. Silver is particularly preferred for its advantageous opto-electronic properties in the near UV and visible spectrum range, relatively low cost, and simplicity of processing. | 07-15-2010 |
20110215001 | Electrochemical Removal of Arsenic - The present invention provides for a system for removing arsenic from an arsenic contaminated aqueous solution, and its use thereof. The system comprises an anode comprising iron and a cathode comprising iron or an electricity conducting metal that is electropositive relative to iron in contact with the arsenic contaminated aqueous solution. The system is used by running an electric current through the water via the anode and cathode to cause the formation of iron (hydr)oxide from the iron of the anode which then forms an insoluble arsenic-iron (hydr)oxide complex which can be separated from the aqueous solution. | 09-08-2011 |
20120017429 | Process for the Preparation of an Electrode from a Porous Material, Electrode Thus Obtained and Corresponding Electrochemical System - Process for the preparation of electrodes from a porous material making it possible to obtain electrodes that are useful in electrochemical systems and that have at least one of the following properties: a high capacity in mAh/gram, a high capacity in mAh/liter, a good capacity for cycling, a low rate of self discharge, and a good environmental tolerance. | 01-26-2012 |
20140370395 | MODIFIED CARBON BLACK MATERIALS FOR LITHIUM-ION BATTERIES - A lithium (Li) ion battery comprising a cathode, a separator, an organic electrolyte, an anode, and a carbon black conductive additive, wherein the carbon black has been heated treated in a CO | 12-18-2014 |
20140374265 | PROCESS FOR THE PREPARATION OF AN ELECTRODE FROM A POROUS MATERIAL, ELECTRODE THUS OBTAINED AND CORRESPONDING ELECTROCHEMICAL SYSTEM - Process for the preparation of electrodes from a porous material making it possible to obtain electrodes that are useful in electrochemical systems and that have at least one of the following properties: a high capacity in mAh/gram, a high capacity in mAh/liter, a good capacity for cycling, a low rate of self-discharge, and a good environmental tolerance. | 12-25-2014 |
