LITHIUM ANTIMONIDE SULFIDE AS LI CONDUCTIVE COMPOUNDS FOR THE APPLICATION OF THICK COATING LAYER IN LI METAL BATTERY AND SOLID ELECTROLYTE IN ALL-SOLID-STATE LITHIUM BATTERIES

Lithium antimony sulfide compounds having lithium ion conductivity of at least 10S/cm are described. The materials are useful as coatings of lithium metal anodes to preevent dendrite formation and provide lithium metal batteries having high energy density.
