Lithium-ion highly conducting Li6PS5Cl argyrodite-type solid electrolyte was prepared by a facile solution process using pyridine solvent as the reaction medium. During the synthesis process, an excess amount of P2S5 was added to suppress impurity peaks and enhance the ionic conductivity. Powder X-ray diffraction analyses were carried out to analyze the crystalline phase and purity of the prepared Li6PS5Cl solid electrolyte. In addition, laser Raman spectroscopy and XPS were employed to confirm the formation of Li6PS5Cl solid electrolyte. Highly conductive Li6PS5Cl solid electrolyte was obtained following a series of optimization processes, and it was found that the Li6PS5Cl-15 P2S5 solid electrolyte shows a high ionic conductivity value (4.3 mS cm–1) at room temperature. We have used cyclic voltammetry (CV), DC polarization, and galvanostatic charge–discharge techniques to study the electrochemical performance of the selected Li6PS5Cl-15 P2S5 solid electrolyte.

使用吡啶溶剂快速合成高导电 Li6PS5Cl Argyrodite 型固体电解质
以吡啶溶剂为反应介质，采用简便的溶液法制备锂离子高导电性Li 6 PS 5 Cl 菱沸石型固体电解质。在合成过程中，加入过量的P 2 S 5以抑制杂质峰并提高离子电导率。进行粉末X射线衍射分析以分析制备的Li 6 PS 5 Cl固体电解质的晶相和纯度。此外，采用激光拉曼光谱和XPS 证实了Li 6 PS 5 Cl 固体电解质的形成。高导电性 Li 6 PS 5经过一系列优化工艺获得了Cl固体电解质，发现Li 6 PS 5 Cl-15 P 2 S 5固体电解质在室温下具有较高的离子电导率值（4.3 mS cm -1 ）。我们使用循环伏安法 (CV)、直流极化和恒电流充放电技术来研究所选 Li 6 PS 5 Cl-15 P 2 S 5固体电解质的电化学性能。
