  • Publication number: 20250323313
    Abstract: A sulfide-based solid electrolyte with an argyrodite crystal structure is represented by the formula Li7?x?3ySbyPS6?xHax, where Ha is one or more halogen elements selected from F, Cl, Br, I, and their combinations, is disclosed. The sulfide-based solid electrolyte comprises a substituted antimony (Sb) element in Wyckoff position 48h of the argyrodite crystal structure instead of Li. The sulfide-based solid electrolyte exhibits a downshifted argyrodite Raman peak compared to an electrolyte without antimony substitution. The disclosed solid electrolyte may be synthesized using a ball milling process to ensure uniform distribution of staring materials and achieve a disordered crystal structure that enhances lithium ion conductivity, pellet density, and fracture strength. The disclosed solid electrolyte can be used in lithium-ion batteries, which are suitable for vehicle applications.
