abstract = {Their suggested stability towards high-voltage cathode
materials makes halide-based solid electrolytes currently an
interesting class of ionic conductors for solid-state
batteries. Especially the LiMn2O4 spinel cathode active
material is of interest due to its slightly higher nominal
voltage and more resilience to overcharging compared to
LiCoO2 and LiNixMnyCozO2 cathodes. Typically, a standard
ratio of active material to solid electrolyte is used in
composites for solid-state batteries. However, for ideal
transport properties, and thus to achieve balanced and
optimal partial-conductivities, this ratio needs to be
re-optimized each time the material basis is changed. In
this work, we show transport in the composite measured
through both DC polarization as well as transmission line
modeling of the impedance spectra. By balancing the partial
transport parameters of the composite, an optimum capacity
of the solid-state batteries is achieved. This work shows
characterization and optimization of transport is required
for unlocking the full potential of solid-state batteries.},
