Japanese Patent JP7083043

B2

The present invention discloses a solid-state electrolyte and a preparation method and application thereof, the solid-state electrolyte comprises membrane material(s) and electrolyte salt(s), the organic phase of the membrane material(s) comprises a three-dimensionally interconnected interface and has a specific interfacial area greater than or equal to 1×10⁴ cm²/cm³, and the electrolyte salt(s) is dissolved in the organic phase. The preparation method of the solid-state electrolyte comprises: spraying the polymeric material solution onto the selected receiving surface using electrostatic spinning technique to form a three-dimensional structure, and optionally, at the same time, spraying the dispersion liquid of the inorganic particles onto the selected receiving surface using electrostatic spraying technique, then treating under pressure to give the membrane material(s), and then dropwise adding or spraying the electrolyte salt(s) solution into the membrane material(s) or immersing the thin film in the electrolyte salt(s) solution. The roomtemperature conductivity of the solid-state electrolyte of the present disclosure is up to over 10^-3 S/cm, does not depend on the addition of special polymers or fillers, and has the advantages of simple preparation, low cost, and wide source of raw materials, etc..
