The electrical energy storage systems have attracted much attention for the past few decades because of the association with the development of alternative energy sources and the gradual depletion of oil resources around the world. From this point of view, the development of clean and highly efficient energy storage systems are becoming an even more urgent need. As an electrochemical energy storage device, rechargeable lithium batteries have been the dominant power sources for portable electronic devices due to the highest energy density achievable in the secondary batteries. They are also being pursued intensively for automotive and stationary storage applications. Although state-of-the art cathode materials for high power lithium-ion batteries may be based on the lithium manganese spinel oxide, improvements of the cathode performance using new concepts are needed. The design of safe, high power density, long life, and low cost alternatives to LiCoO2 is critical for the success of lithium-ion technology for vehicle applications. The choice of the electrolyte is also a major issue for high voltage spinel cathode materials. It must have a large electrochemical window to permit 5V reversible cycling without compromising on the ionic conductivity and rate performance. The thermal runaway poses a tremendous safety issue. Diffusion limited low temperature performance and high current charge and discharge and finally the manufacturing costs are limiting the technology. Understanding and controlling the formation of solid electrolyte interphase (SEI) is very important in the surface modified anodes and cathodes. Improving the batteries for electric vehicles (EV), including hybrid electric (HEV) and plug-in electric (PEV) vehicles, is key to improving vehicles' economic, social, and environmental sustainability in the world.
This symposium will focus on both the scientific and technological aspects of various forms of secondary batteries including lithium-ion, lithium-air, sodium-ion, lithium-sulfur systems. Emphasis will be on design and development of new materials, novel architectures, mechanistic understanding of energy storage processes, system design and development and existing and future applications. The symposium would provide an excellent forum for scientists and engineers from academia, national laboratories and industry to present the latest findings in various energy storage technologies. In addition, the symposium will provide a venue for fruitful interaction and exchange of ideas. It would also educate students and researchers in the nationally and globally important area of energy storage technologies.
