Abstract

Abstract : We report the liquid-phase synthesis of sulfide solid electrolytes from Li2 S and P2 S5 using anisole at 200–300 °C under microwave irradiation, in which β-Li3 PS4 and Li7 P3 S11 were directly precipitated in anisole in 30 min. Abstract : We report the liquid-phase synthesis of sulfide solid electrolytes from Li2 S and P2 S5 using anisole at 200–300 °C under microwave irradiation, in which β-Li3 PS4 and Li7 P3 S11 were directly precipitated in anisole in 30 min. Anisole afforded reasonable reactivity toward Li2 S and P2 S5 to form β-Li3 PS4 and Li7 P3 S11 powders at 200–300 °C. Moreover, a Li6 PS5 Cl precursor solution was synthesized from a Li3 PS4 –anisole suspension by adding ethanol, Li2 S, and LiCl. The proposed synthesis using anisole is advantageous as a simple, short-time process and would be applicable for the production of all-solid-state batteries.
