  • Publication number: 20220376263
    Abstract: The present disclosure relates to a nano-engineered coating for cathode active materials, anode active materials, and solid state electrolyte materials for reducing corrosion and enhancing cycle life of a battery, and processes for applying the disclosed coating. Also disclosed is a solid state battery including a solid electrolyte layer having a solid electrolyte particle coated by a protective coating with a thickness of 100 nm or less. The protective coating is obtained by atomic layer deposition (ALD) or molecular layer deposition (MLD). Further disclosed is a solid electrolyte layer for a solid state battery, including a porous scaffold coated by a first, solid electrolyte coating. The solid electrolyte coating has a thickness of 60 ?m or less and a weight loading of at least 20 wt. % (or preferable at least 40 wt. % or at least 50 wt. %). Further disclosed is a cathode composite layer for a solid state battery.

  • Patent number: 8343888
    Abstract: Precursor cations of A and B elements of an ABO3 perovskite in aqueous solution are formed as an ionic complex gel with citric acid or other suitable polybasic carboxylic acid. The aqueous gel is coated onto a desired catalyst substrate and calcined to form, in-situ, particles of the crystalline perovskite as, for example, an oxidation catalyst on the substrate. In one embodiment, a perovskite catalyst such as LaCoO3 is formed on catalyst supporting cell walls of an extruded ceramic monolith for oxidation of NO in the exhaust gas of a lean burn vehicle engine.
