Ionic conductivity and thermodynamic properties of lithium orthozirconate-based solid electrodes

The lithium zirconates are promising materials for separators of high temperature electrochemical power sources. Regions of stability of solid solutions Li₈ZrO₆ – LiScO₂ and stability fields in the system Li₈ZrO₆, – Li₅AlO₄ have been found. Transport properties of the lithium scandate and solid solutions in the systems Li₈ZrO₆, – LiScO₂ and Li₈ZrO₆ – Li₅AlO₄ were investigated. Equilibrium concentrations of products of thermal decomposition and products of interaction with lithium metal were calculated for most conductive compositions.
