Analysis of Lithium-Ion Mobility in Oxide-Halide Composite Electrolytes Using 2D Exchange NMR, K. Sugii (NIMS) et al.

One major challenge in the practical application of oxide solid electrolytes is their limited plasticity. Recently, the use of composite electrolytes, which combine solid electrolytes with halides, has been explored as a strategy to improve mechanical deformability. In this study, we investigated a composite electrolyte consisting of a garnet-type oxide and a halide using pulsed-field gradient NMR, magic-angle spinning NMR, and two-dimensional exchange spectroscopy NMR. These NMR approaches provide a powerful means of elucidating ion-conduction mechanisms in complex composite electrolytes and are expected to contribute to further progress in the development of solid-state battery materials.
