      abstract     = {The exploitation of high-capacity conversion-type materials
                      such as sulfur in solid-state secondary batteries is a dream
                      combination for achieving improved battery safety and high
                      energy density in the push toward a sustainable future.
                      However, the exact reason behind the low rate-capability,
                      bottlenecking further development of solid-state
                      lithium–sulfur batteries, has not yet been determined.
                      Here, using neutron imaging, the spatial distribution of
                      lithium during cell operation is directly visualized and it
                      is shown that sluggish macroscopic ion transport within the
                      composite cathode is rate-limiting. Observing a reaction
                      front propagating from the separator side toward the current
                      collector confirms the detrimental influence of a low
                      effective ionic conductivity. Furthermore, irreversibly
                      concentrated lithium in the vicinity of the current
                      collector, revealed via state-of-charge-dependent
                      tomography, highlights a hitherto-overlooked loss mechanism
                      triggered by sluggish effective ionic transport within a
                      composite cathode. This discovery can be a cornerstone for
                      future research on solid-state batteries, irrespective of
                      the type of active material.},
