The increase of global demand on energy, coupled with the depletion of fossil fuel and environmental concerns, has driven more research on utilization of renewable energies from wind and solar. However, transforming the intermittent renewable energy into reliable electricity requires an efficient energy storage system (ESS), which depends on the successful development of various types of battery systems. Among different battery systems, the electrolytes have played a critical role in the cell performance, since they are the primary source of ionic species determining the rate capability, and also mediate the electrochemical window of the electrolyte and the formation of solid electrolyte interphase (SEI) at the electrodes determining the cycling stability.In this talk, I will report on our recent development in electrolytes with promising properties for applications in both lithium and magnesium ion batteries.[1-4] Acknowledgements : This research was supported by the U.S. Department of Energy's Office of Basic Energy Science, Division of Materials Sciences and Engineering.
