Ion Conductors and Energy Storage Materials

2011 Glass & Optical Materials Division Spring Meeting

As the push towards renewable energy sources advances, there is an equally critical need for energy storage systems to assist in leveling the variations that are inherent to such renewable sources as wind and solar energy. One particularly promising approach is to use high energy density battery and super capacitor systems. Both of these systems depend critically upon high conductivity, safe, reliable and inexpensive electrolyte separators. Glasses, glass-ceramics, and ceramics have shown significant advantages over organic liquid electrolytes that are common in the typical lithium batteries on the market today. However, these advantages such as high conductivity, non-flammability, and resistance to electrode dendrite growth also come with some disadvantages. This session is targeted to highlight the significant progress in developing new solid electrolytes for energy storage applications with the goal of advancing these materials in such applications as wind and solar energy storage. Oral and poster presentations are sought in the broad area of glassy, glass-ceramic, and ceramic solid electrolytes that describe the fundamentals of ion transport, the structures of the host matrix to foster facile ion transport, the experimental techniques to examine the ion conductivity and the atomic level structures of these materials, the applications of these materials in solid state batteries, such a Li-air cells, and super capacitors, and the performance of solid electrolyte based energy storage systems in application.
