  • Microwave plasma CVD of NANO structured tin/carbon composites
    Patent number: 8221853
    Abstract: 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.
    Type: Grant
    Filed: August 28, 2009
    Date of Patent: July 17, 2012
    Assignee: The Regents of the University of California
    Inventors: Marek Marcinek, Robert Kostecki

  • Graphitized Carbon Coatings for Composite Electrodes
    Publication number: 20080206484
    Abstract: 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.
