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 (LiLaZrO). The method includes preparing nanoparticles comprising lanthanum zirconate (LaZrO-np) via pyrolysis-mediated reaction of lanthanum nitrate (La(NO)) and zirconium nitrate (Zr(NO)). The method also includes pyrolyzing a solid-state mixture comprising the LaZrO-np, lithium nitrate (LiNO), and aluminum nitrate (Al(NO)) to give the LiLaZrOand thereby prepare the lithium-ion conducting garnet. A lithium-ion conducting garnet prepared via the method is also disclosed.

An electrode material includes a lithium active material composition. The lithium active material composition includes lithium and an active anode material. The lithium active material composition is coated with a lithium ion conducting passivating material, such that the electrode material is lithiated and pre-passivated. An electrode and a battery are also disclosed. Methods of making an electrode material, electrode and battery that are lithiated and pre-passivated are also disclosed.
