  • Forming gas treatment of lithium ion battery anode graphite powders
    Patent number: 8834829
    Abstract: The invention provides a method of making a battery anode in which a quantity of graphite powder is provided. The temperature of the graphite powder is raised from a starting temperature to a first temperature between 1000 and 2000° C. during a first heating period. The graphite powder is then cooled to a final temperature during a cool down period. The graphite powder is contacted with a forming gas during at least one of the first heating period and the cool down period. The forming gas includes H2 and an inert gas.
    Type: Grant
    Filed: August 28, 2012
    Date of Patent: September 16, 2014
    Assignee: UT-Battelle, LLC
    Inventors: Cristian Ion Contescu, Nidia C. Gallego, Jane Y. Howe, Harry M. Meyer, III, Edward Andrew Payzant, David L. Wood, III, Sang Young Yoon, Matthew R. Denlinger

  • Adsorbent sheet material for parallel passage contactors
    Patent number: 7077891
    Abstract: An adsorbent material fabricated into a reinforcement-free, self-supported coherent thin sheet and configured for use as a parallel passage contactor element in adsorption/separation applications with gases and liquids is disclosed. The adsorbent sheet material is obtained by enmeshing fine adsorbent particulates in a polymer binder. Particulates include but are not limited to carbon particles, inorganic oxides particles, or ceramic particles, or synthetic polymer resin particles. The adsorbent sheet advantageously contains a large volume percentage of active adsorbent particles.

The adsorbent sheet material is obtained by enmeshing fine adsorbent particulates in a polymer binder. Particulates include but are not limited to carbon particles, inorganic oxides particles, or ceramic particles, or synthetic polymer resin particles, where the characteristic length of particles is in the range from 0.01 &mgr;m to 100 &mgr;m. Particles of nano scale and mixtures of particle sizes may be advantageously incorporated. The adsorbent sheet advantageously contains a large volume percentage of active adsorbent particles.
