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.

  • Patent number: 10446289
    Abstract: A method to provide enhanced electrical conductivity to the biocomposite material in which fibrous materials are initially combined and mixed with a polymer base. As the fibrous material and polymer are mixed or compounded, molecular bonds form between the fibrous material and the polymer. At this stage of the process the conductive material and/or particles are added to the mixture because the molecular bonds have formed in the biocomposite material, and the conductive particles cannot interfere with the bonding between the fibrous material and the polymer. The conductive particles are encapsulated by the biocomposite material such that the biocomposite mixture is formed with enhanced electrical conductivity properties, while not detrimentally affecting any of the other enhanced properties of the biocomposite material based on the molecular bonding between the fibrous material and the polymer.
