abstract = {Solid-state batteries present a promising technology to
overcome the energy density limitations of lithium-ion
batteries. However, achieving a high areal loading in
cathodes without introducing significant transport
limitations remains a key challenge, particularly in thick
electrodes. In this work, we study the impact of a
three-layer graded cathode design on the performance of a
$LiNi_{0.83}Co_{0.11}Mn_{0.06}O_2$ (NCM83)$/ Li_6PS_5Cl$
(LPSCl) composite cathode using a combination of experiments
and microstructure-resolved simulations. An increased LPSCl
content at the separator and higher NCM83 content toward the
current collector improve effective charge transport,
resulting in better rate performance and reduced
overpotentials at high current densities. This comprehensive
experimental and theoretical study demonstrates that the
optimization of cathode design has the potential to
significantly enhance the performance of solid-state
batteries.},
