The purpose of the present study is the preparation of sulfide-based lithium ion conductive solid electrolyte from liquid phase. Powders of sulfide-based solid electrolyte (SE) with high lithium concentration were dissolved into N-methylformamide (NMF) and a homogeneous solution was obtained. The NMF solution was dried at 150°C for 3 hours under vacuum to obtain precipitates. The ionic conductivity of the precipitates was 3×10^<-6>S cm^<-1>. Sulfide-based SE was coated onto positive electrode particles by using an NMF solution of SE.The all-solid-state cell using the electrode particles coated with the SE showed good charge-discharge behavior.

本研究的目的是从液相制备硫化物基锂离子导电固体电解质，将高锂浓度的硫化物基固体电解质（SE）粉末溶解在N-甲基甲酰胺（NMF）中并形成均匀溶液。将获得的NMF溶液在150℃下真空干燥3小时以获得沉淀物的离子电导率。使用SE的NMF溶液将3×10 ^ -6 S cm ^ -1 涂覆到正极颗粒上。使用涂覆有SE的电极颗粒的全固态电池显示。良好的充放电行为。
