  • COMPOSITE SOLID STATE ELECTROLYTE AND LITHIUM ION BATTERY CONTAINING THE SAME
    Publication number: 20210253852
    Abstract: A composite solid state electrolyte comprises a polymer electrolyte material, a ceramic ion conductor, and a functionalized coupling agent selected to be compatible with the ceramic ion conductor and the bulk polymer compound. The polymer electrolyte material comprises a bulk polymer compound and a lithium salt. The functionalized coupling agent has a backbone that is structurally similar to the bulk polymer compound.
