摘要： This invention provides a highly electrically conductive sheet molding compound (SMC) composition and a fuel cell flow field plate or bipolar plate made from such a composition. The composition comprises a top sheet, a bottom sheet, and a resin mixture sandwiched between the top sheet and the bottom sheet. At least one of the top sheet and bottom sheet comprises a flexible graphite sheet, which has a substantially planar outer surface having formed therein a fluid flow channel. Further, the resin mixture comprises a thermoset resin and a conductive filler present in a sufficient quantity to render the flow field plate electrically conductive enough to be a current collector (preferably with a conductivity no less than 100 S/cm). Preferably, both the top and bottom surfaces are flexible graphite sheets, each having a substantially planar outer surface having therein a fluid flow channel formed by embossing. These two flexible graphite sheets are well-bonded by the middle resin mixture layer to form a highly conductive bipolar plate, which is particularly useful for proton exchange membrane fuel cell applications.

摘要： This invention provides a vehicle powered by a surface-mediated cell (SMC)-based power source, comprising a vehicle frame, at least a wheel supporting the frame or a propeller connected to the frame, a drive unit connected to the wheel or propeller, and a power source electrically connected to the drive unit, wherein the power source contains at least a surface-mediated cell. The vehicle can be a micro-EV (using the SMC for the stop-start function), HEV, plug-in HEV, all-electric vehicle, power-assisted bicycle, scooter, motorcycle, tricycle, automobile, wheelchair, fork lift, golf cart, specialty vehicle, bus, truck, train, rapid-transit vehicle, boat, or air vehicle. The ultra-high power density enables the SMC to provide pulsed power or increased current demands when the vehicle is accelerating or hill-climbing. The SMC also enables the power source to recuperate the braking energy when the vehicle decelerates, brakes, or simply moves down-hill.

摘要： Disclosed is a method of exfoliating a layered material (e.g., graphite and graphite oxide) to produce nano-scaled platelets having a thickness smaller than 100 nm, typically smaller than 10 nm, and often between 0.34 nm and 1.02 nm. The method comprises: (a) subjecting the layered material in a powder form to a halogen vapor at a first temperature above the melting point or sublimation point of the halogen at a sufficient vapor pressure and for a duration of time sufficient to cause the halogen molecules to penetrate an interlayer space of the layered material, forming a stable halogen-intercalated compound; and (b) heating the halogen-intercalated compound at a second temperature above the boiling point of the halogen, allowing halogen atoms or molecules residing in the interlayer space to exfoliate the layered material to produce the platelets. Alternatively, rather than heating, step (a) is followed by a step of dispersing the halogen-intercalated compound in a liquid medium which is subjected to ultrasonication for exfoliating the halogen-intercalated compound to produce the platelets, which are dispersed in the liquid medium. The halogen can be readily captured and re-used, thereby significantly reducing the impact of halogen to the environment. The method can further include a step of dispersing the platelets in a polymer or monomer solution or suspension as a precursor step to nanocomposite fabrication.

摘要： A specific embodiment of the present invention is a process for continuously producing a porous solid film of spacer-modified nano graphene platelets for supercapacitor electrode applications. This process comprises: (a) dissolving a precursor material in a solvent to form a precursor solution and dispersing multiple nano graphene platelets into the solution to form a suspension; (b) continuously delivering and forming the suspension into a layer of solid film composed of precursor material-coated graphene platelets overlapping one another, and removing the solvent from the solid film (e.g., analogous to a paper-making, mat-making, or web-making procedure); (c) continuously converting the precursor material into nodules bonded to surfaces of graphene platelets to form a porous solid film composed of spacer-modified graphene platelets; and (d) continuously collecting the porous solid film on a collector (e.g., a winding roller). The roll of porous solid film (mat, paper, or web) can then be cut into pieces for used as supercapacitor electrodes.
