Structural Analysis of Li₇La₃ZrSnO₁₂ as a Solid Electrolyte for all Solid-State Batteries

Abstract:

Li₇La₃ZrSnO₁₂ was successfully prepared by conventional solid-state synthesis. Diffraction data show that the prepared sample has a mixture of two different phases. Both phases have tetragonal crystal symmetry but two different space groups, which are I41/acd and I4/mmm. Rietveld refinements were performed by using the models of the initial structures based on Li₇La₃Zr₂O₁₂ (I41/acdz) and Li₇La₃Ce₂O₁₂ (I4/mmm). It used to quantify the ratio between those two phases by employing Relative Intensity Ratio (RIR) technique. Crystal structure analysis showed that atomic arrangement in Li₇La₃Zr₂O₁₂ (I41/acdz) has more connected 3D tunnel for Li ions migration compared to Li₇La₃Ce₂O₁₂ (I4/mmm) that only connected tunnel at the edge of unit cell. Therefore, the existence of tetragonal phase with the space group of I4/mmm may resulting low ionic conductivity of Li ions at room temperature.
