الإجراء التجريبي

Lithium sulfide (Li2S) and phosphorus sulfide (P2S5) were used as the material composition, and lithium fluoride (LiF) was used as the fluoride. The powder of them was placed in a glove box in an atmosphere of argon, and 0.3828 g Li2S, 0.6172 g P2S5 and 0.01 g LiF were weighed and then these were mixed in an agate mortar. At this time, the ratio of Li2S and P2S5 was 75:25 on a molar basis. In addition, the amount of LiF added was 6.5 mole percent on a fluorine basis with respect to the solid electrolyte material to be obtained. Subsequently, the mixed composition was put into a 45 ml zirconia pot, zirconia balls were further put into the pot and then the pot was completely hermetically sealed. The pot was mounted on a planetary ball milling machine. Then, mechanical milling was performed at a rotational speed of 370 rpm for 40 hours. After that, the solid electrolyte material (Li2S—P2S5-based solid electrolyte material that contains fluorine) was obtained.
