Patent number: 11581570Abstract: Provided herein are methods of forming solid-state ionically conductive composite materials that include particles of an inorganic phase in a matrix of an organic phase. The organic phase includes a cross-linked polyurethane network. The methods involve forming the composite materials from a precursor that is cross-linked in-situ after being mixed with the particles. The cross-linking occurs under applied pressure that causes particle-to-particle contact. Once cross-linked, the applied pressure may be removed with the particles immobilized by the polymer matrix. The polyurethane network is configured for easy processability of uniform films and may be characterized by a hard phase content of at least 20%.Type: GrantFiled: January 7, 2019Date of Patent: February 14, 2023Assignee: Blue Current, Inc.Inventors: Joanna Burdynska, Alexander Teran, Benjamin Rupert, Eduard Nasybulin, Richard Hoft, Simmi Kaur Uppal

Publication number: 20220255116Abstract: Provided herein are compositions of solid-state ionically conductive composite materials that include particles of an inorganic phase in a matrix of an organic phase having a positive thermal coefficient of expansion. When the temperature of the composition is below a cutoff temperature Tc, the composition is ionically conductive and may be used as an electrolyte. As the temperature increases above Tc, the organic phase expands and reduces the ionic conductivity of the composition.Type: ApplicationFiled: June 26, 2020Publication date: August 11, 2022Applicants: Blue Current, Inc., Blue Current, Inc.Inventors: Kevin Wujcik, Joanna Burdynska, Irune Villaluenga
