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%.
