      abstract     = {Li10GeP2S12 (LGPS) is the fastest known Li-ion conductor to
                      date due to the formation of one-dimensional channels with a
                      very high Li mobility. A knowledge-based optimization of
                      such materials for use, for example, as solid electrolyte in
                      all-solid-state batteries requires, however, a more
                      comprehensive understanding of Li ion conduction that
                      considers mobility in all three dimensions, mobility between
                      crystallites and different phases, as well as their
                      distributions within the material. The spin alignment echo
                      (SAE) nuclear magnetic resonance (NMR) technique is suitable
                      to directly probe slow Li ion hops with correlation times
                      down to about 10−5 s, but distinction between hopping
                      time constants and relaxation processes may be ambiguous.
                      This contribution presents the correlation of the 7Li spin
                      lattice relaxation (SLR) time constants (T1) with the SAE
                      decay time constant τc to distinguish between hopping time
                      constants and signal decay limited by relaxation in the τc
                      distribution. A pulse sequence was employed with two
                      independently varied mixing times. The obtained
                      multidimensional time domain data was processed with an
                      algorithm for discrete Laplace inversion that does not use a
                      non-negativity constraint to deliver 2D SLR–SAE
                      correlation maps. Using the full echo transient, it was also
                      possible to estimate the NMR spectrum of the Li ions
                      responsible for each point in the correlation map. The
                      signal components were assigned to different environments in
                      the LGPS structure.},
