摘要：

In this study, we demonstrate the influence of the additives molybdenum trioxide (MoO3) and phosphorus oxynitride (PON) on the ionic conductivity of the oxide solid electrolyte Li2O-LiF-P2O5. The latter is used for surface modification of the lithium-ion batteries electrode materials and as the solid electrolyte with higher ionic conductivity for all-solid-state batteries. Furthermore, we report the optimal content of the additives MoO3 and PON of 1.5 wt% and 10 mol%, respectively, in the structure of the solid electrolyte Li2O-LiF-P2O5 which provides higher ionic conductivity (9.15 10(-6) S cm(-1) and 2.61 10(-6) S cm(-1), respectively) compared to the solid electrolyte Li2O-LiF-P2O5 without additives (4.4 10(-7) S cm(-1)) at room temperature.
