Abstract: The present invention relates to vanadium oxide and methods of controlling reaction processes for making such materials (e.g., powders). In particular embodiments, the method includes control of oxygen partial pressure in order to kinetically control the oxidation species of the crystalline vanadium oxide material. Other methods, uses, systems, protocols, and coatings are also described.

Abstract: The present invention is directed to a higher power, thin film lithium-ion electrolyte on a metallic substrate, enabling mass-produced solid-state lithium batteries. High-temperature thermodynamic equilibrium processing enables co-firing of oxides and base metals, providing a means to integrate the crystalline, lithium-stable, fast lithium-ion conductor lanthanum lithium tantalate (La1/3-xLi3xTaO3) directly with a thin metal foil current collector appropriate for a lithium-free solid-state battery.

Abstract: Compositions and methods for making rare earth metal-Ba2Cu3O7-? films are described. The composition includes a barium (Ba) metal-organic compound, one or more rare earth metal organic compounds and a copper (Cu) metal-organic compound. The composition also includes a halogen. For example, the composition can include a halogenated organic solvent. The composition also includes a solvent having a boiling point greater than approximately 230° C. The precursor solution can also include a low-viscosity solvent that does not react with the halogenated solvent to produce water. A high-viscosity compound can also be included to enable the formation of thicker films. The resulting precursor solution can be deposited on a substrate, pyrolyzed at a heating rate greater than 50° C./minute, and crystallized to produce smooth, sheer films. Films greater than 100 nm in thickness can be produced with transport Jc values of 4×106 A/cm2 at 77° K on various substrates.
