The solid electrolytes Li2O–LiF–Li2WO4–B2O3 with enhanced ionic conductivity for lithium-ion battery

Abstract

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.
