      abstract     = {To achieve the commercialization of solid-state-batteries
                      (SSBs), solid electrolyte properties need to be further
                      improved. The hybrid solid electrolyte (HSE) approach is
                      expected to combine the favorable properties of different
                      solid electrolyte classes and is therefore systematically
                      investigated. Mixing low amounts of thiophosphate or oxide
                      filler particles (FP) into a polyethylene oxide (PEO)
                      polyethylene glycol (PEG) and lithium salt
                      bis(trifluoromethane)sulfonimide (LiTFSI) matrix cannot
                      improve the electrochemical properties. Silanization of the
                      thiophosphate FPs significantly increases the ionic
                      conductivity to 0.1 mS cm−1 at room temperature
                      compared to 0.017 mS cm−1 for a pure PEO solid
                      electrolyte. Moreover, a correlation between the intrinsic
                      conductivity of the FPs and the resulting conductivity of
                      the HSE is observed. Also, the functionalization is
                      successfully transferred to oxide FPs. In addition to an
                      equally significant increase in ionic conductivity, a strong
                      influence of the crystallite size of the FPs on the
                      resulting ionic conductivity of the HSE was found. The
                      discovered effect of FP surface structure on overall HSE
                      conductivity indicates a participation of the FP surface in
                      ion transport and emphasizes the need for tailored filler
                      design in HSE applications.},
