      abstract     = {Lithium argyrodite superionic conductors with the general
                      formula Li$_6$PS$_5$X (X = Cl, Br, I) have been intensively
                      investigated in recent years and successfully adopted in the
                      field of solid-state batteries (SSBs). The transport
                      properties of argyrodite solid electrolytes (SEs) usually
                      strongly depend on the degree of occupational disorder.
                      Increasing disorder through complex doping or substitution
                      has been shown to directly affect ionic conductivity.
                      Herein, we explore a high-entropy lithium argyrodite of
                      nominal composition
                      Li$_{6.6}$[P$_{0.2}$Si$_{0.2}$Sn$_{0.2}$Ge$_{0.2}$Sb$_{0.2}$]S$_5$I.
                      This material can be readily prepared by mechanochemistry.
                      Using complementary diffraction techniques, nuclear magnetic
                      resonance spectroscopy, and charge-transport measurements,
                      we show that upon tailoring crystallinity and defect
                      concentration by post-annealing at temperatures up to 220
                      °C, a high room-temperature ionic conductivity of about 0.9
                      mS cm$^{−1}$ (∼4.4 mS cm$^{−1}$ bulk conductivity) can
                      be achieved. Both the as-prepared and annealed (at 220 °C)
                      samples were tested in pellet-stack SSB cells. The
                      mechanochemically prepared glass–ceramic SE was found to
                      exhibit superior performance, even outperforming
                      commercially available Li$_6$PS$_5$Cl. Collectively, the
                      results highlight the importance of considering structural
                      aspects across different length scales when optimizing the
                      properties of lithium argyrodites for SSB applications.},
