In conclusion, this work highlights the importance of balanced transport in composite cathodes and shows that the "transport quality" of the electrode can be qualitatively The loss in rate capability with increased areal loading motivates studies that focus on processing optimization and particle size matching as strategies to improve transport in cathodes with high areal loading. This is because improving the partial ionic conductivity will lower the δ-parameter independent on electrode thickness and applied current density. Moreover, this work highlights the importance of investigating electrodes with realistic energy densities already on the lab-scale. Thereby, the potential of new cell chemistries in outlook to application can be evaluated from the start and problems can be targeted before upscaling of the technology is attempted.
