Synthesis of Al-Doped LLZO Thin-Tape Electrolytes for Solid-State Batteries Using Flame-Assisted Spray Pyrolysis

A method of synthesis of aluminum-doped Li_{6.25}Al_{0.25}La_3Zr_2O_{12} (Al-LLZO) can include preparing a precursor solution by dissolving lithium nitrate, aluminum nitrate, zirconium (IV) oxynitrate, and lanthanum nitrate in stoichiometric amounts according to the composition Li_{6.25}Al_{0.25}La_3Zr_2O_{12} in water, and decomposing droplets by passing through a co-flow burner. Also disclosed is a method of produce producing a thin-tape comprising Al-LLZO.
