Provided herein are ionically conductive solid-state compositions that include ionically conductive inorganic particles in a matrix of an organic material. The resulting composite material has high ionic conductivity and mechanical properties that facilitate processing. In particular embodiments, the ionically conductive solid-state compositions are compliant and may be cast as films. In some embodiments of the present invention, solid-state electrolytes including the ionically conductive solid-state compositions are provided. In some embodiments of the present invention, electrodes including the ionically conductive solid-state compositions are provided. The present invention further includes embodiments that are directed to methods of manufacturing the ionically conductive solid-state compositions and batteries incorporating the ionically conductive solid-state compositions.

Compliant solid-state ionically conductive composite materials and method for making same

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 methods involve forming the composite materials from a precursor that is polymerized in-situ after being mixed with the particles. The polymerization occurs under applied pressure that causes particle-to-particle contact. In some embodiments, once polymerized, the applied pressure may be removed with the particles immobilized by the polymer matrix. In some implementations, the organic phase includes a cross-linked polymer network. Also provided are solid-state ionically conductive composite materials and batteries and other devices that incorporate them. In some embodiments, solid-state electrolytes including the ionically conductive solid-state composites are provided. In some embodiments, electrodes including the ionically conductive solid-state composites are provided.

Polymerized in-situ hybrid solid ion-conductive compositions

Provided herein are multilayer solid-state lithium ion batteries and methods of fabrication. In some embodiments, units of preformed cell elements and a current collector (of either the anode or cathode) are stacked. The preformed cell element includes a double-sided electrode, with separator/electrode on both sides of the double-sided electrode. The double-sided electrode may be an anode or a cathode. During the stacking process, the preformed cell elements are laminated to a cathode current collector or an anode current collector, as appropriate.

Solid-state lithium ion multilayer battery and manufacturing method

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%.

Polyurethane hybrid solid ion-conductive compositions

Provided herein are functionally substituted fluoropolymers suitable for use in liquid and solid non-flammable electrolyte compositions. The functionally substituted fluoropolymers include perfluoropolyethers (PFPEs) having high ionic conductivity. Also provided are non-flammable electrolyte compositions including functionally substituted PFPEs and alkali-metal ion batteries including the non-flammable electrolyte compositions.
