Abstract:
The distribution of degradation products, before and after cycling, within common sulfide-based solid electrolytes (β-Li3PS4, Li6PS5Cl and Li10GeP2S12) was mapped using Raman microscopy. All composite electrodes displayed the appearance of side reaction products after the initial charge-discharge cycle, located at the site of a LiNi0.6Mn0.2Co0.2O2 particle.
