  • Rapid pyrolysis to form super ionic conducting lithium garnets
    Patent number: 11535525
    Abstract: A method of preparing a lithium-ion conducting garnet via low-temperature solid-state synthesis is disclosed. The lithium-ion conducting garnet comprises a substantially phase pure aluminum-doped cubic lithium lanthanum zirconate (Li7La3Zr2O14). The method includes preparing nanoparticles comprising lanthanum zirconate (La2Zr2O7-np) via pyrolysis-mediated reaction of lanthanum nitrate (La(NO3)3) and zirconium nitrate (Zr(NO3)4). The method also includes pyrolyzing a solid-state mixture comprising the La2Zr2O7-np, lithium nitrate (LiNO3), and aluminum nitrate (Al(NO3)3) to give the Li7La3Zr2O14 and thereby prepare the lithium-ion conducting garnet. A lithium-ion conducting garnet prepared via the method is also disclosed.
