      abstract     = {Given the inherent performance limitations of
                      intercalationbasedlithium-ion batteries, solid-state
                      conversion batteries arepromising systems for future energy
                      storage. A high specific capacityand natural abundancy make
                      iron disulfide (FeS2) a promisingcathode active material. In
                      this work, FeS2 nanoparticles wereprepared solvothermally.
                      By adjusting the synthesis conditions,samples with average
                      particle diameters between 10 nm and 35 nmwere synthesized.
                      The electrochemical performance was evaluated insolid-state
                      cells with a Li-argyrodite solid electrolyte. While
                      thereduction of FeS2 was found to be irreversible in the
                      initial discharge,a stable cycling of the reduced species
                      was observed subsequently.A positive effect of smaller
                      particle dimensions on FeS2 utilization wasidentified, which
                      can be attributed to a higher interfacial contact areaand
                      shortened diffusion pathways inside the FeS2 particles.
                      Theseresults highlight the general importance of
                      morphological design toexploit the promising theoretical
                      capacity of conversion electrodes insolid-state batteries.},
