Electrochemical Activation of LiGaO₂: Implications for Ga-Doped Garnet Solid Electrolytes in Li-Metal Batteries.

ABSTRACT: Ga-doped Li₇La₃Zr₂O₁₂ garnet solid electrolytes exhibit the highest Li-ion conductivities among the oxide-type garnet-structured solid electrolytes, but instabilities toward Li metal hamper their practical application. The instabilities have been assigned to direct chemical reactions between LiGaO₂ coexisting phases and Li metal by several groups previously. Yet, the understanding of the role of LiGaO₂ in the electrochemical cell and its electrochemical properties is still lacking. Here, we are investigating the electrochemical properties of LiGaO₂ through electrochemical tests in galvanostatic cells versus Li metal and complementary ex situ studies via confocal Raman microscopy, quantitative phase analysis
