Abstract

The development of all solid-state lithium batteries is reliant on suitable high performance solid state electrolytes. Here, we present the synthesis and ionic conductivity of the In-And Y-doped li₆hf₂o₇ materials; Li _6+xHf _2-xM _x O₇ (M = In ³⁺, Y ³⁺). Microwaveassisted synthesis was used to give phase pure material after heating for 4 hours at 850?C. The ionic conductivity of the materials is increased with the insertion of interstitial lithium ion within the structure from 0.02 to 0.25 mS cm^-1at 174?C and the activation energy for ionic conduction is lowered from 0.97(4) eV to 0.42(3) eV with respect to the undoped material.
