Nuclear Magnetic Resonance Studies of Imidazolium-Based Ionic Liquids and Garnet-Type Li7La3Zr2O12

<p>Advancements in electrochemical energy storage materials are critical in the development and utilization of renewable energy technologies. These advancements involve obtaining a better understanding of electrochemical mechanisms and properties through scientific research towards an improved energy storage technology. Nuclear magnetic resonance (NMR), is a sensitive and selective method to probe particle dynamics (magnetic relaxation, diffusometry, etc.) and material structures (spectroscopy) down to the atomic level. In this work, several NMR techniques are employed to study imidazolium-based ionic liquids and garnet-type inorganic materials. These are being studied due to their potential use as safer alternatives to organic solvent-based electrolytes in lithium-ion batteries. X-ray techniques have been used to explore the structural properties of garnet typed Li₇La₃Zr₂O_{12<strong> </strong>}solid electrolyte. The result yields a deeper molecular level understanding and therefore gives valuable insight into how these materials can be developed further for energy storage and conversion applications.</p>
