With the ever increasing demand for next generation electrochemical energy storage cells to achieve higher performance, often overlooked are the safety issues arising from electrolytes. Liquid electrolytes, while inherently having high ionic conductivity, are comprised of lithium salts dissolved in flammable carbonate-based organic solvents. These highly flammable solvents, coupled with the concern for packaging derived from the leakage of these solvents, have become key issues for battery researchers. To alleviate these problems, research on electrolytes has been pervasive in both academia and industrial sectors. In this talk, I will briefly introduce our recent development of gel-state electrolytes utilizing silsesquioxane-based materials and ionic liquids. Silsesquioxanes, with chemical formula [RSiO1.5]n, provide a unique alternative to conventional polymer electrolytes, as the organic/inorganic functionality not only imbues non-leaking mechanical robustness, thermal stability, and high electrochemical stability, but also exhibits complete solution processability and unique ion transport behavior. Also, electrochemical performances of self-assembled ionic liquids crystal based ionogels will be discussed.
