Understanding Interfaces at the Positive and Negative Electrodes on Sulfide-Based Solid-State Batteries.

ABSTRACT: Despite the high ionic conductivity and attractive mechanical properties of sulfide-based solid-state batteries, this chemistry still faces key challenges to encompass fast rate and long cycling performance, mainly arising from dynamic and complex solid-solid interfaces. This work provides a comprehensive assessment of the cell performance-determining factors ascribed to the multiple sources of impedance from the individual processes taking place at the composite cathode with high-voltage LiNi_0.6Mn_0.2Co_0.2O₂, the sulfide argyrodite Li₆PS₅Cl separator, and the Li metal anode. From a multiconfigurational approach and an advanced deconvolution of electrochemical impedance signals into distribution of relaxation times, we disent
