Reassessing the bulk ionic conductivity of solid-state electrolytes

Abstract

The ionic conductivity of solid-state electrolytes is a crucial factor for futuristic battery applications. It is measured via the bulk resistance of the pellet, which not only depends on the properties of the materials but also on the physical parameters including frequency. It is shown in this study that the high-frequency point affects the ionic conductivity more than other variables. With a growing number of solid-state battery studies, we believe that now is the time to establish a common standard to measure ionic conductivity of the solid-state electrolytes for Li-ion batteries.
