Replacing the liquid electrolyte in conventional lithium-ion batteries with thin-film solid-state lithium-ion conductors is a promising approach for increasing energy density, lifetime, and safety. In particular, Li7La3Zr2O12is appealing due to its high lithium-ion conductivity and wide electrochemical stability window. Further insights into thin-film processing of this material are required for its successful integration into solid-state batteries. In this work, we investigate the phase evolution of Li7–3xGaxLa3Zr2O12in thin films with various amounts of Li and Ga for stabilizing the cubic phase. Through this work, we gain valuable insights into the crystallization processes unique to thin films and are able to form dense Li7–3xGaxLa3Zr2O12layers stabilized in the cubic phase with high in-plane lithium-ion conductivities of up to 1.6 × 10–5S cm–1at 30 °C. We also note the formation of cubic Li7La3Zr2O12at the relatively low temperature of 500 °C. |
