20210403340, Dec 30, 2021

Filed:

Jul 2, 2021

Appl. No.:

17/366990

Inventors:

Jon Mark Weller - Phoenix AZ, US
Candace Chan - Phoenix AZ, US

International Classification:

C01G 25/00
H01M 10/0525
H01M 10/0562

Abstract:

Synthesizing lithium lanthanum zirconate includes combining a reagent composition with a salt composition to yield a molten salt reaction medium, wherein the reagent composition comprises a lithium component, a lanthanum component, and zirconium component having a lithium:lanthanum:zirconium molar ratio of about 7:3:2; heating the molten salt reaction medium to yield a reaction product; and washing the reaction product to yield a crystalline powder comprising lithium lanthanum zirconate.

Abstract:

Fabricating a layer including lithium lanthanum zirconate (LiLaZrO) layer includes forming a slurry including lanthanum zirconate (LaZrO) nanocrystals, a lithium precursor, and a lanthanum precursor in stoichiometric amounts to yield a dispersion including lithium, lanthanum, and zirconium. In some cases, the dispersion includes lithium, lanthanum, and zirconium in a molar ratio of 7:3:2. In certain cases, the slurry includes excess lithium. The slurry is dispensed onto a substrate and dried. The dried slurry is calcined to yield the layer including lithium lanthanum zirconate.

Abstract:

Nanosized cubic lithium lanthanum zirconate is synthesized by forming a solution including an organic compound and compounds of lithium, lanthanum, and zirconium; drying the solution to yield a solid; and heating the solid in the presence of oxygen to pyrolyze the organic compound to yield a product comprising nanosized cubic lithium lanthanum zirconate.
