Hydrolytic and oxidative stability of sulfide solid electrolytes

Year: 2025

Type: article

Abstract: The hydrolytic and oxidative stability of sulfide solid electrolytes Li7P3S11 and Li3PS4 at different humidity of the gas environment (air and argon) was studied. It was found that increasing the air humidity the oxidation rate of sulfide solid electrolytes also increases. It was shown that the oxidation rate of sulfide solid electrolytes depends on their composition. Thus, Li7P3S11 electrolyte has higher oxidation stability in the humid air compared to Li3PS4. Lithium sulfate is the main oxidation product of sulfide solid electrolytes.
