Three-dimensional Core@Shell Nano-Array Electrodes for Integrated Lithium-Ion Microbatteries

Mao Y., Sun X., Li Q., Lv Y., University of Texas-Pan American, US

In micro/nanoelectromechanical systems (MEMS/NEMS) and biomedical devices, the desired on-board power storage and delivery occur in exceptionally small geometric scales, where amount of energy stored on given footprint (J/mm2) precedes that in either unit weight [...]

Large Scale Energy Storage with Thermal Matrix Energy Storage

Sutherland S., Lynch G., Pietsch T., Kelvin Storage Technologies, Inc, US

The presentation reviews the design and technical innovations for storing energy as heat in a graphite core at temperatures far above the melting point of steel. The high temperatures reached, over 4000F, enable storing vast [...]

Rechargeable Nanofluid Electrodes for High Energy Density Flow Battery

Timofeeva E.V., Katsoudas J.P., Segre C.U., Singh D., Argonne National Laboratory, US

Nanomaterial suspensions in liquids (nanofluids) are the new expanding area in nanotechnology, with applications as wide as biomedical, lubrication, thermal management, energy generation, energy conversion, and energy storage. Variety and unique characteristics of nanomaterials allow [...]

Novel Electrolytes for Supercapacitors

Stiemke F., Blumenröder B., Schubert T.J.S., IOLITEC Ionic Liquids Technologies Inc., US

Supercaps using ionic liquids (ILs) as novel electrolytes have gained much attention because of their interesting profiles of physical and chemical properties , such as tunable viscosities and conductivities, chemical and thermal stability as well [...]

Flexible and Turnable Biomimetic Pyruvate Dehydrogenase Complex (PDC) Supercapacitors

Thornton J., Christelle C., Chen E.T., Advanced Biomimetic Sensors, Inc., US

Flexible supercapacitors are challenged by low energy density and short discharge time. We report a new type of biomimetic pyruvate dehydrogenase complex (BIMPDC) supercapacitors having the self-assembling membrane (SAM) offer orders of magnitude higher in [...]

Pseudocapacitive random and aligned nano-porous electrode materials for supercapacitors

Saruhan B., Gönüllü Y., Arndt B., German Aerospace Center, DE

Commercial electric double layer capacitors store energy in an electric field. This is caused by charged particles arranged on two electrodes consisting mostly of carbon, in the form of a double layer. Such double layer [...]

High Performance Supercapacitors Based on Thermal Reduced Graphene Oxide

Perego D., Franz S., Bestetti M., Borioli C., Politecnico di Milano, IT

THERMALLY REDUCED GRAPHENE OXIDE BASED SUPERCAPACITORS HAVE BEEN FABRICATED AND TESTED. ELECTRODES BASED ON METAL SUBSTRATE (TI, AISI304, NI, AL) WERE FABRICATED BY EITHER BY ELECTROPHORESIS AND SPRAY COATING OF GRAPHENE OXIDE SOLUTIONS. ELECTROCHEMICAL TEST [...]

AC Conductivity, Dielectric and Electric Modulus Studies of Nanocrystalline LiCoO2 Particles

Nageswara Rao B., Venkateswarlu M., Satyanarayana N., Pondicherry University, IN

Nanocrystalline LiCoO2 particles were successfully synthesized using acryl amide assisted polymeric citrate process.The formation of phase pure LiCoO2 was confirmed from XRD results. FTIR results confirmed the formation LiCoO2 structure. SEM results showed the formation [...]

Carbon Combustion Synthesis of Lithium Cobaltate

Hobosyan M., Mamyrbaeva Y., Martirosyan K.S., University of Texas at Brownsville, US

We recently developed a novel process Carbon Combustion Synthesis of Oxides (CCSO) to rapidly produce high purity, submicron, porous powders of complex oxides. The crystalline LiCoO2 nanoparticles were synthesized by carbon combustion synthesis, and characterized [...]

Rechargeable Lithium-ion Batteries For Wireless Smart Designs

Mourzagh D., Daniel L., Chami M., Rouault H., Fusalba F., CEA, FR

Wireless communication is today considered as a disruptive technology. Indeed, even if wired systems can easily achieve 100% of reliability, it induces high amount of wiring, which has non negligible impact on the mass and [...]
