Interface and grain boundary resistance of a lithium lanthanum titanate (Li3xLa2/3-xTiO3, LLTO) solid electrolyte

摘要

Advanced experimental setups and measurement techniques are crucial for investigating and systematically improving interface characteristics. In this study we introduce an interface-cell, which allows the systematic analysis of liquid/solid electrolyte interfaces via four-point measurements. The functionality of this setup is demonstrated by analysing the impact of parameter variations on the aqueous interface of lithium lanthanum titanate (Li3xLa2/3-x-TiO3, LLTO) solid electrolytes as used in Lithium-air batteries.
