Nanocomposite of graphene and metal oxide materials
Nanocomposite materials comprising a metal oxide bonded to at least one graphene material. The nanocomposite materials exhibit a specific capacity of at least twice that of the metal oxide material without the graphene at a charge/discharge rate greater than about 10 C
TITANIA-GRAPHENE ANODE ELECTRODE PAPER
We used a commercial titania (Degussa P-25) to prepare titania-graphene composite papers. cationic ammonium surfactants stabilized the titania and graphene in aqueous solutions.the homogeneous composite suspensions containing 80-90 wt% titania were filtered and extra surfactants were removed by thermal treatment at 400C under H2/Ar for 3 h. The composite powder was mixed with 7.0 wt% PTFE to make a paper. Electrochemical test showed steady and high performance (150 mAh/g).
Thick Electrodes Including Nanoparticles Having Electroactive Materials and Methods of Making Same
Electrodes having nanostructure and/or utilizing nanoparticles of active materials and having high mass loadings of the active materials can be made to be physically robust and free of cracks and pinholes. The electrodes include nanoparticles having electroactive material, which nanoparticles are aggregated with carbon into larger secondary particles. The secondary particles can be bound with a binder to form the electrode.

SYSTEMS AND PROCESSES FOR CONVERSION OF ETHYLENE FEEDSTOCKS TO HYDROCARBON FUELS
Systems, processes, and catalysts are disclosed for obtaining fuel and fuel blends containing selected ratios of open-chain and closed-chain fuel-range hydrocarbons suitable for production of alternate fuels including gasolines, jet fuels, and diesel fuels. Fuel-range hydrocarbons may be derived from ethylene-containing feedstocks and ethanol-containing feedstocks.
SYSTEMS AND PROCESSES FOR CONVERSION OF ETHYLENE FEEDSTOCKS TO HYDROCARBON FUELS
PNNL has invented processes for converting ethanol and or ethylene to distillate range hydrocarbon fuels. The processes form normal and isoparaffins with very little aromatic and cyclic compound content, catalysts have long lifetimes, and processes are expected to have high carbon efficiencies.
CATALYST AND METHOD EMBODIMENTS FOR MAKING PARA-XYLENE AND ORTHO-XYLENE (iEdison No. 0685901-20-0047)
We have developed a chemistry to generate p-xylene from ethanol. Theinnovation involves the conversion of ethanol derived acetaldehyde to p-methylbenzaldehyde overmixed oxide catalyst followed by the conversion to p-xylene via hydrogenolysis (ethanol →acetaldehyde → p-methyl benzaldehyde → p-xylene). Among aromatics, the production distributioncontains only p-xylene, o-xylene and benzene. Typical p-xylene synthesis (both conventional andrenewable) process contains range of aromatics (e.g. benzene, toluene, o-xylene, ethyl benzene, mxylene,p-xylene etc.) that needs to be purified via the expensive separation process.The simple aromatic stream provides to major advantages over the conventional and other renewabletechnologies.1) The aromatic mixture to p-xylene separation/purification steps become simpler and cheaper2) Enables to build a modular plant to meet the local renewable feedstock availability and reduces thefeedstock transportation cost
Methods and apparatuses for making cathodes for high-temperature, rechargeable batteries
The approaches for fabricating cathodes can be adapted to improve control over cathode composition and to better accommodate batteries of any shape and their assembly. For example, a first solid having an alkali metal halide, a second solid having a transition metal, and a third solid having an alkali metal aluminum halide are combined into a mixture. The mixture can be heated in a vacuum to a temperature that is greater than or equal to the melting point of the third solid. When the third solid is substantially molten liquid, the mixture is compressed into a desired cathode shape and then cooled to solidify the mixture in the desired cathode shape.
