abstract = {The Na+ ionic conductivity of ball milled
Na3−xIn1−xZrxCl6 rises with increasing Zr content, while
that in the subsequently annealed Na3−xIn1−xZrxCl6
compounds reaches a maximum conductivity at an intermediate
substitution degree (x = 0.5). To clarify the underlying
mechanism causing the differing trends, the local structure
and coherence length of the ball milled Na3−xIn1−xZrxCl6
solid solutions were investigated by pair distribution
function analyses. The structural evolution in the ball
milled Na3−xIn1−xZrxCl6 series resembles those found in
their annealed counterpart, however, its structural
coherence length decreases with higher Zr content. By
further investigating the transport properties using
impedance spectroscopy, this work uncovers a correlation
between the coherence length and the ionic conductivity in
ball milled Na3−xIn1−xZrxCl6, in which lower structural
coherence leads to higher ionic transport. This work
indicates an influence of the microstructure beyond unit
cell scale onto macroscopic transport properties in these
sodium-conducting halide solid electrolytes.},
