Atomic Layer Deposition Innovations in Li-Ion Battery Technology

Buechler K., Groner M., George S., Jung Y.S., Cavanaugh A., ALD NanoSolutions, Inc., US

Atomic layer deposition (ALD) can enhance the stability and utility of lithium ion batteries. Nanothick coatings on electrodes, electrode powders and even separator materials can significantly improve the performance of batteries, especially at high temperatures [...]

Hydrogen storage by reduced graphene oxide and graphene-like nanosheets decorated with Fe nanoclusters

Hudson M.S.L., Srivastava O.N., Simizu S., Sankar S.G., Central University of Tamil Nadu, IN

Here, we present the high pressure hydrogen sorption isotherm up to 50 bar of graphene oxide (GO) reduced by thermal reduction (TR-GO), chemical reduction (CR-GO) and graphene like nanosheets decorated with Fe nanoclusters (Fe-GS). GO [...]

Hydrogen Recharge Dynamics and Vessel Design for Porous Silicon Storage Media

Schubert P.J., Urbanek A., IUPUI, US

Porous silicon as a storage media can store up to 7.1% hydrogen by weight [1,3]. The round-trip energy difference is 1.2 kJ/mol, but the as-synthesized energy barrier requires 410 C for complete thermal discharge [2]. [...]

3-Dimensional Carbon Nanotube-Graphene Structure for Flexible Li-ion Battery

Kang C., Baskaran R., Mumukshu P., Choudhary N., Choi1 W., University of North Texas, US

Flexible electronics have attracted great attention for use in next-generation portable devices and their major applications include roll-up displays, wearable devices, active radio frequency identification (RFID) tags, integrated circuit smart cards and implantable medical devices. [...]

Metal Organo-Clays as potential adsorbents for hydrogen storage

Azzouz A., Nousir S., Bouazizi N., Roy R., University of Quebec at Montreal, CA

Metal-Organo-Clays (MOC) are novel microporous matrices that can be synthesized via the in-situ formation of Cu, Fe or Pd nanoparticles in montmorillonite-supported polyol dendrimers. This is a new concept that has scarcely been tackled so [...]

Secondary Use Energy Storage

Starke M., Irimger P., Ollis B., Andrews G., Karlson P., Thabiappah S., Rosenfeld P., Massin S., Oak Ridge National Laboratory, US

This study presents the testing of a community energy storage system composed of repurposed used electric or plug-in hybrid electric vehicle (EV/PHEV) battery packs. The expectation is that the vehicular batteries will be replaced with [...]

A Study on the System Configuration for the Flywheel Energy Storage Device to be Applied to the Railway System

Lee J-H., Korea Railroad Research Institute, KR

A system configuration to be applied to the railway system using flywheel energy storage system to store regenerative energy which is produced during the braking period of the train is presented. The proposed FESS (Flywheel [...]

Nanostructured Acetylcholinesterase (ACHE) Memristor/Memcapacitor Mimicks Brachyhypopomus Electric Fish’s Signal-Cloaking Behavior

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

The Brachyhypopomus Electric (BHE) fish is known for its signal-cloaking behavior that allows it to avoid predators by shifting its electroreceptive pulses from low frequency to less detectable high-frequency through a phase-delay “head-tail” Electric Organ [...]

MWCNTs/metal oxide nanocomposite as potential material for supercapacitors application in acidic and neutral media

Adekunle A.S., Ozoemena K.I., Agboola B.O., Ebenso E.E., North-West University, ZA

Carbon based supercapacitor electrodes have been attractive due to their high surface area and porous nature. Studies have shown that the carbon nanotube-metal oxide (CNT-MO) nanocomposite modified electrodes exhibited huge capacitive current in some electrolytes. [...]
