Solid State NMR Studies of Materials for Electrical Energy Storage: Supplemental and Continuing Support
Abstract
Nuclear Magenetic Resonance (NMR) spectroscopy methods will be used to understand ionic transport in materials critical to energy storage and generation systems. This continuation and expansion of current research activities covers several kinds of energy storage materials: polymer dielectrics for thin film capacitors and electrolytes for electrochemical capacitors and batteries. Alternatives to BOPP under investigation include polycarbonate and polyvinylidene fluoride (PVdF) under a variety of preparation conditions. For electrochemical capacitors novel liquid electrolytes, and for batteries, both liquid and solid polymer electrolytes will be studied. As in all past ONR-funded projects over the last three decades, this investigation will leverage the efforts of numerous collaborators who will provide characterized materials for a suite of NMR measurements conducted at Hunter College. Multinuclear and Fast Field Cycling NMR (FFCNMR) will be used to study molecular level processes that will ultimately be correlated with electrical or electrochemical properties of the materials. Fundamental properties of ionic liquids with crosscutting applications will also be investigated. Key Words: Polymer dielectrics, liquid and solid electrolytes, electrochemical capacitors, batteries, ionic liquids, NMR Spectroscopy, Fast Field Cycling NMR (FFCNMR).
