Abstract: 

The oxidative and hydrolytic stability of the precursors Li2S and P2S5 for the synthesis of sulfide solid electrolytes was studied using gravimetric analysis. The study was conducted in air with different water content and dry argon. It was established that the water content in air significantly affects the stability of materials. Li2S and P2S5 are unstable even in air with the water content of 5 ppm. Moreover, it was found that the oxidative-hydrolytic stability of Li2S depends on the presence of impurities.

Key words:
