  • Patent number: 7393587
    Abstract: A finstock material for heat dissipation, which includes at least one sheet of flexible graphite sandwiched between two outer layers.
    Type: Grant
    Filed: September 17, 2004
    Date of Patent: July 1, 2008
    Assignee: Graftech International Holdings Inc.
    Inventors: Daniel Witold Krassowski, Gary D. Shives, Julian Norley, Robert Anderson Reynolds, III
  • Patent number: 7166912
    Abstract: An isolated thermal interface is presented. The inventive interface includes a flexible graphite sheet having two major surfaces, at least one of the major surfaces coated with a protective coating sufficient to inhibit flaking of the particles of graphite.
    Type: Grant
    Filed: April 5, 2001
    Date of Patent: January 23, 2007
    Assignee: Advanced Energy Technology Inc.
    Inventors: Jing-Wen Tzeng, Daniel Witold Krassowski
  • Patent number: 6613252
    Abstract: A method of manufacturing material suitable for the construction of a component of a fuel cell, such as a flow field plate or electrode. Uncured resin impregnated flexible graphite sheet is ground into particles. Without re-expanding the particles, and without adding further resin to the particles, the particles are molded into the form of the desired material. The material is then cured. Additives may be mixed with the particles to improve the properties of the material.
    Type: Grant

    Date of Patent: September 2, 2003
    Assignee: Advanced Energy Technology Inc.
    Inventors: Julian Norley, Michael Lee Warddrip, Daniel Witold Krassowski, Robert Angelo Mercuri
  • Patent number: 6555271
    Abstract: An anode for a lithium-ion battery is presented as well as a process for producing an anode for a lithium-ion battery. The anode is formed from a generally continuous sheet of particles of exfoliated graphite having a thickness of no more than about 350 microns, itself or in a laminate with a metallic substrate. The process involves laminating particles of exfoliated graphite to a metallic substrate, such that the particles of exfoliated graphite form a generally continuous sheet of graphite having a thickness of no more than about 350 microns. The inventive anode reduces or eliminates capacity fading due to contact loss and has superior permeability to lithium.
    Type: Grant

    Date of Patent: April 29, 2003
    Assignee: Graftech Inc.
    Inventors: Ronald Alfred Greinke, Daniel Witold Krassowski, Neal David Phillips
  • Patent number: 6521369
    Abstract: An electrode for an electrochemical fuel cell is provided. More particularly, an electrode formed of a sheet of a compressed mass of expanded graphite particles having a plurality of transverse fluid channels passing through the sheet between first and second opposed surfaces of the sheet, is provided. The size, shape and/or placement of the channels, and/or the density of the sheet, is engineered so as to reduce or minimize flooding in the fuel cell.

  • Publication number: 20020109125
    Abstract: The invention presented relates to a process for providing increased electrical and/or thermal conductivity to a material, and to the materials prepared by the process. More particularly, the invention relates to a process involving applying particles of expanded graphite to a substrate or material in order to increase its conductivity. The particles of expanded graphite can be applied to the substrate or material through coating of the substrate with a composition comprising the expanded graphite particles, or by incorporating particles of expanded graphite into the substrate or material itself.
