Title

Experimental visualization of ionic percolation pathways in the fast lithium conductor Li7-3xGaxLa3Zr2O12 and a deuterium-exchanged sample

Abstract

Li-stuffed garnet oxides are promising solid electrolyte materials for lithium batteries. Recently, we reported on a Ga-substituted Li7La3Zr2O12 with lithium ion conductivity reaching 1.3mS/cm at room temperature (the highest obtained for garnet oxides, to date). However, ceramic superionic Li conductors readily suffer from atmospheric corrosion and, in particular Li-H exchange. Much debate has centre on whether the lodged protons progressively block the lithium conduction paths or may exhibit co-mobility in the crystal lattice. Here we seek to clarify this by directly exploring ionic percolation pathways before and after 2D-exchange, as a function of temperature.
