Scope:

The widespread integration of renewable, intermittent energy sources such as wind or solar is dependent upon the development of efficient large-scale energy storage systems for load-levelling the electric grid. Similarly, the acceptance of plug-in hybrid electric (PHEV) - and especially pure electric vehicles (EV) - hinges on the availability of large-scale, safe, low-cost energy storage batteries to provide driving ranges that greatly exceed the psychological barrier of > 100 miles (~160km). These future developments are coupled. Peak renewable energy stored “off the grid” could be ideally used to charge automotive energy storage systems at off-peak hours such as night. As power utilities work to meet renewable-energy goals and add more solar and wind power to their portfolios, energy storage to help level out the intermittent power from those sources is becoming ever more critical. To meet the future challenges of energy storage, new materials chemistry, and especially new nano-materials chemistry, is essential. This symposium highlights on-going advances in this area on batteries, redox flow cells and novel large scale energy storage devices.

More specifically, Li-ion battery is one of the most promising technologies for high energy density devices, while supercapacitors occupy a privileged position for high power systems. Lithium air batteries represent a class of potentially ultrahigh energy density power sources and are currently under development with many hurdles to overcome. Lithium-sulfur batteries have been receiving particular interest due to the emergence of recent alternatives for improving their cycling lives. Obviously, electrolytes have a strategic position in all these devices, especially when nano-scale and/or safety issues are concerned.

In parallel to this energy- and power-wise research, improvements in terms of nature conservancy are strongly required and open new challenges and exciting perspectives for the next generation of sustainable and "greener" systems.

The proceedings of this symposium will be published in the journal Power Sources by Elsevier.
