摘要

全固态电池电解质的溶液合成作为一种更有效、可扩展的替代方法，受到了广泛的关注。四硫锑酸钠Na3SbS4是一种很有前途的全固态钠离子电池电解质。首次采用二甲亚砜溶剂作为反应介质。Na3SbS4粉体由不规则颗粒凝聚而成，室温下na离子电导率为2.74·10−4 S/cm，活化能低至0.26 eV。目前使用二甲亚砜溶剂的路线将是生产高性能固体电解质的另一种方法。

Synthesis of Na3SbS4 solid electrolyte from dimethyl sulfoxide solvent

As a more effective and scalable substitute for conventional solid-state syntheses, solution synthesis of electrolytes for all solid-state batteries attracts a lot of attention. Sodium tetrathioantimonate Na₃SbS₄ is a promising solid electrolyte (SE) for all-solid-state sodium ion batteries. Dimethyl sulfoxide solvent was used for the first time as a reaction medium. The Na₃SbS₄ powder is made of agglomerated irregular particles, and exhibits a Na-ionic conductivity at room temperature of 2.74·10⁻⁴ S/cm coupled with a low activation energy of 0.26 eV. The current route using dimethyl sulfoxide solvent would be an alternative approach for the production of high-performance solid electrolytes.
