Description:

All-solid-state lithium-ion batteries are a promising next-generation technology because they have higher energy densities than their liquid-electrolyte counterparts. Recently, halogen-rich argyrodite, specifically Li5.4(PS4)(S0.4Cl1.0Br0.6), has been reported to show higher ionic conductivities than other sulfides with argyrodite structures and electrochemical stability against lithium metal. However, the stability of Li5.4(PS4)(S0.4Cl1.0Br0.6) against cathode active materials in all-solid-state batteries has not yet been evaluated. Herein, we report the electrochemical stability of Li5.4(PS4)(S0.4Cl1.0Br0.6) as a solid electrolyte in an all-solid-state battery.
