In this study, it is obtained solid electrolytes 60Li2O.10LiF.10Li2WO4-20B2O3 with content of LiF is 10 mol% and Li2WO4 with 10 mol% exhibit high ionic conductivity of 1.7410-6 S cm-1 compared to the solid electrolyte 50Li2O-20Li2WO4-30B2O3 without LiF is 2.510-7 S cm-1 at room temperature. The obtained solid electrolyte is used as the surface agent of the active material LiCoO2 which displays cycling stability and low electrode resistance via surface stabilization at a high potential of 4.4 V (vs. Li/Li+) at the 1C current density for 100 cycles compared to the pristine material.
