摘　　要：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 Na_(3)SbS_(4) 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.
