7Li NMR spectroscopy is known to be very sensitive to translational motion in solids and therefore highly suited for investigating temperature-dependent Li+ dynamics. A number of different NMR methods are available for choosing the dynamical range of the observed Li+ jump frequencies present in inorganic solid-state electrolytes. This includes 7Li spin-alignment echo NMR spectroscopy, static 7Li lineshape analysis, and 7Li spin-lattice relaxometry that can be used to detect Li+ jumps in the Hz, kHz, and MHz range, respectively. We introduce and discuss these NMR techniques with respect to their theoretical description and practical application to investigate the Li+ dynamics at different time scales for the two solid-state electrolytes Li8SiP4 and Li14SiP6. The data evaluation for all methods is discussed in detail, focusing on the determination of Li+ jump frequencies and activation energies for the investigated self-diffusion processes in a given structure. |
