Solution-synthesis method is attractive for solid electrolytes because it is a facile and scalable process to be used to permeate electrodes and to construct a thin electrolyte coating layer on active materials. In this work, we report Cl-doped Na₃SbS₄ prepared via aqueous-solution approach. Besides decent ionic conductivity, the aqueous-solution approached electrolyte demonstrates an improved interfacial stability toward Na metal compared to the solid-state sintered one because of the residual hydrate, nanosized microstructure, and Cl incorporation. All-solid-state batteries using the solution-prepared electrolytes have enhanced cycling performance, though the performance still needs to be further improved.

溶液合成法对于固体电解质是有吸引力的，因为它是一种容易且可扩展的方法，用于渗透电极并在活性材料上构造薄的电解质涂层。在这项工作中，我们报告了通过水溶液法制备的掺Cl的Na ₃ SbS ₄。除固态离子导电性外，与固态烧结的电解质相比，水溶液法电解质还表现出对Na金属的改进的界面稳定性，这归因于残留的水合物，纳米级微观结构和Cl的引入。尽管仍需要进一步改善性能，但使用溶液制备的电解质的全固态电池具有增强的循环性能。
