Abstract

Tungsten-substituted Na₃SbS₄ shows enhanced ionic conductivity but the role of sintering treatments is not well understood. The effects of sintering on Na_3−xSb_1−xW_xS₄ were examined and found to slightly increase the solubility of W, reduce voids, and possibly increase contact area. Changes in phase composition and morphology play a key role in the performance of Na_3−xSb_1−xW_xS₄ electrolytes.
