Amorphous ionically conductive metal oxides and sol gel method of preparation

Amorphous lithium lanthanum zirconium oxide (LLZO) is formed as an ionically-conductive electrolyte medium. The LLZO comprises by percentage of total number of atoms from about 0.1% to about 50% lithium, from about 0.1% to about 25% lanthanum, from about 0.1% to about 25% zirconium, from about 30% t...

Zusammenfassung:Amorphous lithium lanthanum zirconium oxide (LLZO) is formed as an ionically-conductive electrolyte medium. The LLZO comprises by percentage of total number of atoms from about 0.1% to about 50% lithium, from about 0.1% to about 25% lanthanum, from about 0.1% to about 25% zirconium, from about 30% to about 70% oxygen and from 0.0% to about 25% carbon. At least one layer of amorphous LLZO may be formed through a sol-gel process wherein quantities of lanthanum methoxyethoxide, lithium butoxide and zirconium butoxide are dissolved in an alcohol-based solvent to form a mixture which is dispensed into a substantially planar configuration, transitioned through a gel phase, dried and cured to a substantially dry phase.
