Solid electrolytes are key materials to enable solid-state rechargeable batteries, a promising technology that could address the safety and energy density issues. Here, we report a sulfide sodium-ion conductor, Na<sub>2.88</sub>Sb<sub>0.88</sub>W<sub>0.12</sub>S<sub>4</sub>, with conductivity superior to that of the benchmark electrolyte, Li<sub>10</sub>GeP<sub>2</sub>S<sub>12</sub>. Partial substitution of antimony in Na<sub>3</sub>SbS<sub>4</sub> with tungsten introduces sodium vacancies and t ...[more]
