      abstract     = {All-solid-state lithium–sulfur batteries (ASSLSBs) are
                      emerging as a promising alternative for green energy
                      storage, offering high theoretical capacities and energy
                      densities by using inexpensive materials. To date, ASSLSBs
                      commonly suffer from poor cycle life and sluggish reaction
                      kinetics. A promising active material for ASSLSBs is iron
                      disulfide, $FeS_2$, due to its natural abundance, low cost,
                      and high theoretical capacity (894 $mAh·g^{–1}$) It
                      undergoes a displacement reaction with significant volume
                      changes whose effects can be locally constrained by using
                      small particles. Here, the influence of the positive
                      electrode microstructure on the electrochemical performance
                      of $FeS_2$-based ASSLSBs with Cl-rich argyrodite,
                      $Li_{5.5}PS_{4.5}Cl_{1.5}$, a mechanically soft sulfide
                      solid electrolyte with high ionic conductivity, is
                      investigated. Composites with different microstructures were
                      prepared using three different processing methods (i.e.,
                      hand grinding, ball mill, and mini mill). Their impact on
                      the electrochemical performance was evaluated, revealing
                      that homogeneously submicro-structured composites achieve
                      higher capacities (up to 4.28 $mAh·cm^{–2}$) and capacity
                      retention (87.2\% at the 50th cycle). Furthermore, finely
                      structured composites enhance the in situ formation of
                      active material from the solid electrolyte and increase its
                      accessible reversible capacity. Ex situ analyses (i.e.,
                      SEM-EDS and XPS) at different states of charge show that the
                      morphology of $FeS_2$ evolves forming core–shell like
                      submicro-structures.},
