摘要: The glass–ceramic electrolytes of (100− x)(0.8 Li 2 S· 0.2 P 2 S 5)· x LiI (in mole percent; x= 0, 2, 5, 10, 15, 20, and 30) were prepared by mechanical milling and subsequent heat treatment. Crystalline phases analogous to the thio-LISICON region II or III in the Li 2 S–GeS 2–P 2 S 5 system were precipitated. The thio-LISICON III analog phase was mainly precipitated at the composition x= 0, and the thio-LISICON II analog phase was precipitated in the composition range from x= 2 to 15. The X-ray diffraction peaks of the thio-LISICON II …
