Abstract:

In this review, we introduce the basic principles of solid-state nuclear magnetic resonance (NMR) spectroscopy, focusing on magic angle spinning and cross-polarization, which can reduce or eliminate partial interactions in the nuclear spin system to improve the resolution of NMR spectra. Several solid-state NMR techniques for obtaining ion migration dynamics information are summarized, including pulsed-field gradient NMR, central transition line width analysis, relaxation time analysis, 2D exchange NMR, and spin alignment echo NMR. Further, we review the application of these techniques to a series of typical cases, such as cathode materials, anode materials, LISICON, Thio-LISICON, NASICON, and garnet type solid electrolyte materials. A comparison of the advantages and disadvantages of each technology is also included. Finally, the recent developments in the field of solid-state NMR spectroscopy for the study of the mechanism of ion diffusion in batteries is discussed.

Key words: solid-state NMR, lithium-ion batteries, ionic dynamic, ion diffusion pathway
