摘要：
To realize all-solid-state sodium-ion batteries, the ionic conductivities and stabilities of solid electrolytes must be improved. The sulfide Na3SbS4 electrolyte is known to show a high sodium-ion conductivity of over 10(-3) S cm(-1) at room temperature. In this study, cation-substituted Na3SbS4 solid electrolytes with excess Na or Na vacancies were prepared, and the effects of substitution on the material conductivity were examined. The ionic conductivities of the Na3+xSb1-xMxS4 (M = Si, Ge, Sn) electrolytes, which were doped with excess Na, were lower than that of the Na3SbS4 electrolyte; in contrast, the conductivities of the Na3-xSb1-xMoxS4 electrolytes, which were doped with Na vacancies, were higher. The Na2.88Sb0.88Mo0.12S4 electrolyte showed the highest room-temperature ionic conductivity of 3.9 x 10(-3) S cm(-1) and the lowest activation energy for conduction of 21 kJ mol(-1). To improve the ionic conductivity of the Na3SbS4 electrolyte, introducing Na vacancies instead of excess Na was found to be effective.
