Direct Precursor Route for the Fabrication of LLZO Composite Cathodes for Solid-State Batteries.

ABSTRACT: Solid-state batteries based on Li₇La₃Zr₂O₁₂ (LLZO) garnet electrolyte are a robust and safe alternative to conventional lithium-ion batteries. However, the large-scale implementation of ceramic composite cathodes is still challenging due to a complex multistep manufacturing process. A new one-step route for the direct synthesis of LLZO during the manufacturing of LLZO/LiCoO₂ (LCO) composite cathodes based on cheap precursors and utilizing the industrially established tape casting process is presented. It is shown that Al, Ta:LLZO can be formed directly in the presence of LCO from metal oxide precursors (LiOH, La₂O₃, ZrO₂, Al₂O₃, and Ta₂O₅) by heating to 1050 °
