Composite Li-Ion Anodes from Recycled Silicon

Xu W., Electrochemical Materials, US

Silicon byproducts from sources such as kerf are difficult to use directly as lithium-ion batteries since key parameters such as silicon particle size, surface oxides, and impurities, do not fulfill the requirements for silicon anode [...]

Integration of Flow Batteries into Electric Vehicles: Feasibility and the Future

Katsoudas J.P., Timofeeva E.V., Segre C.U., Singh D., Illinois Institute of Technology, US

Driving range, safety and cost remain the biggest hurdles in the way of mass electric vehicle adoption. To compete with established combustion-engine vehicles, EVs need to have a highly flexible operating capability with minimum downtime. [...]

Market Evaluation for Energy Storage in the United States

Strong Z., Copper Development Association, US

A first-of-its-kind study commissioned by the Copper Development Association Inc. (CDA) evaluate the current and future market for grid energy storage in the U.S. and the associated copper demand in storage applications over the next [...]

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 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. [...]

Capturing and Using CO2 as Feedstock for Clean Chemical Processes Technologies

Demirel Y., University of Nebraska Lincoln, US

Chemical-looping technology for capturing CO2 are discussed with critical assessments of the circulating fluidized bed systems and the packed bed reactor with periodic switching of the feed streams of fuel and air. Beside, some industrial [...]

Commercial pilot for closed-loop wastewater treatment and biofuel production using microalgae

Atwood M., Novoveska L., Sundstrom E., Valdez P., Algae Systems LLC, US

In wastewater treatment, significant energy is used to dilute, discharge, or landfill valuable resources. This situation is untenable due to energy costs and global scarcity of clean water. Algae Systems has developed and patented a [...]

Enhanced fuel cell performance with modified Nafion® membranes

Krishnan L., Yeager G., Clark K., Kerr J., Soloveichik G., Miebach T., GE Global Research, US

The interaction of Nafion® 212 membrane with a carbocyclic fuel, decalin was studied. Decalin treatment of N212 improved vapor sorption and membrane conductivity. In addition a substantial increase of peak power in a H2/Air fuel [...]

Hydrogen Generation from Thermochemical Water-Splitting Using Core Shell Ni-Ferrite/Y2O3 Nanoparticles

Amar V.S., Shende R.V., South Dakota School of Mines & Technology, US

During thermochemical water-splitting process for hydrogen generation,ferritenanoparticles undergo significant grain growth that reduces their surface area and affect the porous morphology. Consequently, hydrogen volume generation diminishes with increase in thermochemical cycles. In order to mitigate [...]
