This project explored the structure and dynamics of novel electrolytes aimed at improving the safety and performance of current and next-generation lithium-based batteries. The work focused on ionic liquids, diluted ionic liquids, and highly concentrated electrolytes, materials that offer improved thermal and electrochemical stability compared to conventional solvent-based systems.
Using neutron and X-ray scattering, the research probed how ions organize and move at mesoscopic length scales—revealing nanostructures and correlated ion motion not found in simple liquids. Complementary measurements of conductivity, viscosity, calorimetry, and Raman spectroscopy were used to connect molecular-scale ordering with macroscopic transport behavior.
The results demonstrated that mesoscale structuring plays a key role in determining ion mobility and electrolyte stability, providing new understanding of how microscopic interactions govern macroscopic properties. This knowledge contributes to the design of advanced electrolytes that can enable safer, more stable, and higher-performance batteries for future energy technologies.
