Advances in nuclear magnetic resonance spectroscopy: case of proton conductive materials

Understanding of molecular dynamics in proton conductive materials in solid-state allows creating materials with increased performance and efficiency. For this purpose, nuclear magnetic resonance (NMR) spectroscopy is a very promising technique due to its atom-level sensitivity. During the last few decades, NMR spectroscopy, especially solid-state NMR (ssNMR) spectroscopy, plays an important role in the characterization of electrolyte materials thus attracting great attention of both the academy and industry sector. This review focuses on the widespread application of NMR and ssNMR spectroscopy for the characterization of proton conductive materials. A view of selected case studies is provided together with the possible development. Besides, the conductivity results obtained using both liquid and ssNMR analysis are discussed and compared with the results obtained by electrochemical impedance spectroscopy.
