A lithium ion battery pack includes a plurality of prismatic lithium polymer cells and one or more graphite heat spreaders. Each spreader has at least two major surfaces and is made of one of a sheet of a compressed mass of exfoliated graphite particles, a graphitized polyimide sheet, or combinations thereof.

Thermal solution for prismatic lithium ion battery pack

A method for preparing resin-impregnated graphite articles, including providing a sheet of compressed particles of exfoliated graphite having two major surfaces; impregnating the sheet with a first resin system to form a resin-impregnated sheet; surface treating the resin-impregnated sheet to form at least one structure on at least one of the major surfaces of the sheet to form a surface treated sheet; and treating the sheet with a second resin system.

Dimensionally stable, leak-free graphite substrate

A substrate useful for the formation of, inter alia, a flow field plate for a proton exchange membrane fuel cell, the substrate formed of at least one resin-impregnated sheet of compressed particles of exfoliated graphite comprising two major surfaces, the substrate having an active area with flow field channels thereon, the sheet of compressed particles of exfoliated graphite having a local web thickness in at least about 50% of its active area that is no more than about 55% greater than the minimum web thickness of the active area of the substrate.

Uniform graphite plate

A flexible graphite sheet exhibiting enhanced isotropy is provided. In addition, an apparatus, system and method for continuously producing a resin-impregnated flexible graphite sheet is also provided.

Flexible graphite article and method of manufacture

A male-female electrode joint is presented, the joint including two joined graphite electrodes having blocked threads and having a seal interposed between the electrodes, the seal composed of a material having an oxidation rate equal to or less than that of the electrodes.

End-face seal for male-female electrode joints

A process for preparing a gas permeable flexible graphite sheet is presented. The process includes providing graphite flakes; admixing the graphite flakes with a sacrificial additive to form a graphite mixture; compressing the graphite mixture into a sheet having sacrificial additive dispersed therethrough; and treating the sheet to at least partially remove the sacrificial additive to form a permeable flexible graphite sheet.

Gas permeable flexible graphite sheet material and process therefor

An improved method enables preparation of articles for a variety of applications, including embossing or otherwise shaping to form a variety of articles. A plurality of thin, preferably resin-impregnated, flexible graphite sheets are arranged to form zones in a composite material having a graded density or other characteristic. Variation of properties between zones in the stock material formed is useful for achieving a desired set of properties in the formation of articles such as those useful in electrochemical fuel cells and double-layer capacitors.

Method for preparing composite flexible graphite material

An end-face seal for graphite electrode joints, including a seal formed of a plurality of individual elements interlocked to form a unitary whole, and formed of a material having an oxidation rate equal to or less than that of the electrodes.

Apparatus for forming a resin impregnated flexible graphite sheet

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 electrode is treated with a water resistant additive sufficient to provide utility as a cathode in an electrochemical fuel cell.

Hydrophobic fuel cell electrode

Fluid permeable graphite article in the form of a perforated flexible graphite sheet having increased electrical and thermal conductivity transverse to the surfaces of the sheet.
