Mechanical properties such as formability and elastic moduli of solid electrolytes are important for the fabrication of all-solid-state batteries and retention of their charge–discharge capacities. In this paper, xNa2S·(100 − x)P2S5 (mol%) sulfide glass electrolytes (x = 50, 67, and 75) were prepared and their formability and elastic moduli were evaluated by an ultrasonic pulse-echo technique and a compression test under uniaxial pressing. The glasses were better densified and showed lower Youngs moduli (15–19 GPa) than the Li2S–P2S5 glasses.
