Abstract
Amorphous solid electrolytes in the system xLi 2O–(1 − x)(0.6Li 2S–0.4P 2S 5) (with x = 0.1, 0.15, 0.2, 0.25, 0.3, 0.35 and 0.4) have been prepared from a mixture of Li 2O, Li 2S and P 2S 5 using a mechanical milling technique at room temperature and in inert atmosphere. The oxysulfide powder mechanically milled for 80 h with x = 0.25 shows an ionic conductivity ( σ) of 2.5 × 10 −4 S cm −1 at 300 K which is the highest in this series. The glass transition temperature ( T g) exhibits a minimum at x = 0.25. Constant volume molecular dynamics was done for all x. Structural and transport results from molecular dynamics (MD) simulation are described. Changes in structure with x and their influence on σ and T g are discussed.
