      abstract     = {The influence of the microstructure on the ionic
                      conductivity and cell performance is a topic of broad
                      scientific interest in solid-state batteries. The current
                      understanding is that interfacial decomposition reactions
                      during cycling induce local strain at the interfaces between
                      solid electrolytes and the anode/cathode, as well as within
                      the electrode composites. Characterizing the effects of
                      internal strain on ion transport is particularly important,
                      given the significant local chemomechanical effects caused
                      by volumetric changes of the active materials during
                      cycling. Here, we show the effects of internal strain on the
                      bulk ionic transport of the argyrodite Li6PS5Br. Internal
                      strain is reproducibly induced by applying pressures with
                      values up to 10 GPa. An internal permanent strain is
                      observed in the material, indicating long-range strain
                      fields typical for dislocations. With increasing dislocation
                      densities, an increase in the lithium ionic conductivity can
                      be observed that extends into improved ionic transport in
                      solid-state battery electrode composites. This work shows
                      the potential of strain engineering as an additional
                      approach for tuning ion conductors without changing the
                      composition of the material itself.},
