  • POROUS GRAPHENE NETWORK ELECTRODES AND AN ALL-CARBON LITHIUM ION BATTERY CONTAINING THE SAME
    Publication number: 20170047588
    Abstract: Systems for the production of graphene oxide sheets are provided. The systems include electro-deposition and spray deposition techniques. The graphene oxide sheets may be used as pre-cursors for the formation of porous graphene network (PGN) anodes and lithiated porous graphene (Li-PGN) cathodes. The method of making PGN electrodes includes thermally reducing a pre-cursor sheet of graphene oxide to provide a PGN anode and exposing the sheet to lithium or a lithium-containing compound to produce a Li-PGN cathode. The Li-PGN cathode and PGN anode may be combined with an electrolyte to provide an “all-carbon” battery that is useful in various applications, such as automotive applications.

  • RAPID MACRO-SCALE SYNTHESIS OF FREE-STANDING GRAPHENE, HIGH PERFORMANCE, BINDER-FREE GRAPHENE ANODE MATERIAL, AND METHODS OF SYNTHESIZING THE ANODE MATERIAL
    Publication number: 20140050910
    Abstract: A method of synthesizing a sheet of graphene oxide paper includes combining graphite oxide with water to form a colloidal suspension of graphene oxide; providing a working electrode and a counter electrode such that the working electrode and the counter electrode are inserted in the colloidal suspension; applying a potentiostatic field until a film of graphene oxide having a predetermined thickness forms on the working electrode; and drying the film to form a graphene oxide paper. The method may also include reducing the graphene oxide to graphene by either photo-thermal reduction or thermal exfoliation. The reduced graphene material exhibits high energy density as well as high power density making it useful as anode material for rechargeable batteries.

  • Miniaturized gas sensors featuring electrical breakdown in the vicinity of carbon nanotube tips
    Publication number: 20060251543
    Abstract: An ionization gas sensor includes a first electrode and a second electrode, such as cathode and anode electrodes. The second electrode is a carbon nanotube film having a carbon nanotube density such that the film behaves as a conducting sheet electrode. The sensor also includes a voltage source electrically connected to the first and to the second electrodes.
