Lithium Environments in Lithium-rich Borogermanate Glasses and Binary Precursor Glasses

Abstract: Previously, our exploration of the Li+ environment in oxide glasses employed the null isotope method on Li2O-TeO2 glasses and revealed variations in Li-O distances depending on composition. Specifically, in compositions with lower Li2O content, we observed two distinct Li-O peaks at 1.99 and 2.11 Å. The shorter peak corresponds to 4-coordinated Li, while the longer peak resembles the Li configuration found in its crystalline counterpart, high-temperature ?-Li2Te2O5. We then studied the more complex xLi2O-yBO1.5-(100-x-y)GeO2 system (x, y = 10, 20, 30) and identified two distinct Li-O peaks at 1.75 and 1.99 Å. The 1.75 Å peak is notably shorter than the typical 4-coordinated Li. We conjectured that these differing distances could be linked to the borate and germanate networks. To validate and expand upon these findings, we wish to extend our investigation into Li2O-BO1.5-GeO2 with higher Li2O content (40 mol%) and to also explore the Li environments within the precursor binary systems Li2O-B2O3 and Li2O-GeO2 at the same Li2O compositions. This comprehensive approach will enhance our understanding of how Li+ coordinates with its neighbouring atoms and establish correlations between its structural configuration and mobility, thereby providing valuable insights for the development of lithium-based solid-state batteries. We will also consider the factors which constrain the resolution of this technique.
