Solid-state batteries are considered as one of the most promising next generations of energy storage technologies with a potential to revolutionize electric vehicles (EVs), due to their high energy density and intrinsic safety . Here, the solid electrolyte is key since it allows the utilization of Li or Si as anode and the possibility to have bi-polar cell configurations. Hence, several solid electrolytes have been explored, whereby most of them fall into two groups : (i) Oxide-based solid electrolytes, such as garnet-type Li7La3Zr2O12 and NaSICON-type Li1+xAlxTi2-x(PO4)3 and (ii) sulfides, such as thio-LISICON-type Li10GeP2S12 (LGPS) and Argyrodite-type Li6PS5Cl (LPSCl). Of most solid electrolytes, LPSCl is considered one of the promising candidates, owing to its high ionic conductivity, favorable mechanical performance, and ease in processing . However, there are significant challenges associated with the energy density, rate capability, and capacity retention of solid-state batteries employing LPSCl . These challenges arise from the interfacial contact-loss during electrochemical cycling as a consequence of volumetric changes in electrodes and the electrochemical stability limitations in the preferred operation voltage range causing undesirable side reactions with high-voltage Ni-rich cathodes, giving rise to fast capacity fade, thus impeding their ultimate commercial realization .
