Seawater Flow Battery as Technology Platform

Grid-level storage of renewable energy using electrolytes from seawater is a platform technology with multiple byproducts and use-case scenarios. The core application is to provide load-leveling for intermittent sources such as wind and solar. Membranes [...]

Rechargeable Lithium-ion Batteries For Wireless Smart Designs

Mourzagh D., Rouault H., Jouanneau S., Daniel L., Chami M., Moreau G., Fusalba F., CEA-Grenoble, 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 [...]

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 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. [...]
