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 LiNi_0.6Mn_0.2Co_0.2O₂ particle.
