Our research group aims to apply advanced solid-state nuclear magnetic techniques, in combination with electrochemical characterisation, to the study of materials of interest as chemical power sources. Lithium ion batteries and proton exchange membrane fuel cells (PEM-FC) provide environmentally friendly energy alternatives. Emerging technologies include sodium ion batteries, and sodium/lithium-air batteries, which are exciting, but so far poorly understood & controlled. Solid-state NMR is well known for its ability to provide site-specific information on structure and dynamics. We utilise multi-nuclear approaches including 7Li, 6Li, 23Na, and 1H, to investigate processes and interactions such as electrochemical transport, ionic conductivity, hydrogen-bonding,and polymer chain ordering or mobility. In recent years, the field of magnetic resonance has experienced rapid technological and methodological growth, allowing a broader range of materials questions to be addressed.
