Solid-state LiNMR with applications to the translational dynamics in ion conductors

An overview of both theoretical and experimental nuclear magnetic resonance (NMR) investigations of translational dynamics in lithium solid-like ion conductors is presented. NMR techniques can be used to reveal details of the slow and ultra-slow dynamics in ion conductors. These techniques allow to obtain site-resolved information in a model-free fashion. The motion of Li ions plays an important role in liquid and solid electrolytes, metals, and electrode materials for which there is both electron and ion conduction. The transition to slow dynamics is monitored by temperature-dependent changes in the line-shape of solid-echo and Jeener Broekaert (JB) echo spectra. NMR investigations of structural aspects of lithium ion conductors allows to review their spin evolution under a well defined static Hamiltonian as well as their spin-relaxation properties.
